Description

Gas turbine engine control device and mobile body

[0001] The present disclosure relates to a gas turbine engine control device and a vehicle such as a gas turbine engine vehicle equipped with the gas turbine engine and the control device.

[0002] In modern society, transportation is indispensable, and various types of vehicles, such as vehicles and aircraft, are used in daily life. Among these vehicles, as exemplified in Patent Document 1, there is known a vehicle that uses a gas turbine to drive a generator, and supplies electric power obtained by this generator to a drive system such as a vehicle drive motor.

[0003] The rotation speed of the gas turbine described above is controlled by a known PID control, as shown in, for example, Patent Documents 2 to 4. For example, Patent Document 2 discloses that when an electrical load is applied, feedback control of the fuel flow rate is performed so that the rotation speed of the gas turbine increases in accordance with the magnitude of the load. More specifically, Patent Document 2 proposes looking up a map from the electrical load to determine a target rotation speed, and PID control of the fuel flow rate so that the actual rotation speed of the gas turbine coincides with this target rotation speed.

[0005] Current technologies, including those disclosed in the above-mentioned patent documents, do not yet satisfy market needs, and the following problems remain. For example, when a gas turbine engine is installed in a vehicle, the gas turbine engine may be installed in the engine compartment near peripheral devices such as a radiator fan and a cooling pump. In this case, like the peripheral devices, a fuel supply mechanism associated with the gas turbine engine is powered by power supplied from an auxiliary battery installed in the vehicle.

[0006] In a vehicle equipped with a fuel supply mechanism, it is expected that the voltage of the auxiliary battery will fluctuate due to changes in current when the peripheral devices are activated. In particular, the inrush current immediately after the peripheral devices are started up is large, and there is a concern that the amount of fuel injected by the fuel supply mechanism will fluctuate when such an inrush current occurs.

[0007] On the other hand, as exemplified in Patent Document 2, the fuel injection amount of the fuel supply mechanism can be corrected by referring to a voltage map. However, if only the normal PID control exemplified in Patent Document 2 is performed, the fuel injection amount will deviate from the expected amount in response to a sudden change such as the above-mentioned inrush current, resulting in large variations in the fuel injection amount.

[0008] The present disclosure has been made in consideration of the above-mentioned problems as an example, and aims to provide a gas turbine engine control device and a mobile body equipped with this control device that can suppress variations in the fuel injection amount in a fuel supply mechanism even when a sudden change in drive voltage occurs in the fuel supply mechanism due to, for example, an inrush current generated in a peripheral device.

[0009] In order to solve the above-described problems, according to one aspect of the present disclosure, there is provided a control device for controlling a gas turbine engine having a fuel supply mechanism that injects fuel into compressed air, the control device comprising: one or more processors; and one or more memories communicably connected to the one or more processors, wherein the processor temporarily increases a gain of PID control that controls the fuel supply mechanism relative to a basic constant when a drive voltage of the fuel supply mechanism fluctuates due to a sudden change in an input current input to the fuel supply mechanism.

[0010] According to the present disclosure, even if a sudden change in drive voltage occurs in the fuel supply mechanism, it is possible to suppress variations in the fuel injection amount in this fuel supply mechanism.

[0012] Next, preferred embodiments of the present disclosure will be described. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted. Furthermore, configurations other than those described in detail below may be supplemented as appropriate with elemental technologies and configurations, including PID control, related to known gas turbine engines, including those described in the patent documents mentioned above.

[0013] 1 and 2 are schematic diagrams respectively showing an example configuration and functional blocks of a gas turbine engine vehicle GTV including a gas turbine 30 and a control device 100 thereof according to this embodiment. The gas turbine 30 and the control device 100 thereof according to this embodiment can be applied to various known mobile bodies such as vehicles, aircraft, and ships. The following description will continue using a vehicle (gas turbine engine vehicle) as an example of the above-mentioned mobile body.

[0014] As shown in Fig. 2, the gas turbine engine vehicle GTV is configured as a four-wheel drive vehicle in which a driving force source 21 generates driving torque for the vehicle and transmits the output driving torque to a left front wheel 3LF, a right front wheel 3RF, a left rear wheel 3LR, and a right rear wheel 3RR (hereinafter collectively referred to as "wheels 3" unless a distinction is required). In this embodiment, the driving force source 21 can be, for example, a well-known electric motor for driving a vehicle, disposed on the front wheel side. This driving force source 21 can output driving torque that is transmitted to a front drive shaft 2F and a rear drive shaft 2R via a transmission, a front wheel differential mechanism 5F, and a rear wheel differential mechanism 5R (not shown).

[0015] The electric motors serving as the driving force source 21 in this embodiment may be arranged one on each of the front and rear wheels, or one electric motor may be arranged for each wheel 3. The gas turbine engine vehicle GTV of this embodiment is configured as a four-wheel drive vehicle, but it may also be a two-wheel drive vehicle in which the electric motor drives either the front or rear wheels. In addition to the electric motor, the driving force source 21 may further include a known internal combustion engine such as a gasoline engine or a diesel engine.

[0016] A power supply system that supplies desired electric power to such driving force source 21 includes, for example, a gas turbine 30 described below, a fuel supply mechanism 40 having a known fuel injection nozzle capable of supplying fuel to this gas turbine 30, a generator 45 such as a known power generation motor that receives driving force from the gas turbine 30 and generates electric power, a known secondary battery BT2 such as a lithium ion secondary battery or a lead storage battery that can store the electric power generated by this generator 45, a known converter 22, and a control device 100 that controls these.

[0017] In this embodiment, the gas turbine 30, fuel supply mechanism 40, and generator 45 are disposed in a known engine room together with the peripheral device 10. Although the engine room housing the gas turbine engine is located in the front of the vehicle in this embodiment, the engine room may be located in the rear. As shown in FIGS. 1 and 2 , the fuel supply mechanism 40 and peripheral device 10 are electrically connected to a known auxiliary battery BT1 installed in the engine room, for example. This allows the fuel supply mechanism 40 and peripheral device 10 to receive the power required for driving from the auxiliary battery BT1. Furthermore, the fuel supply mechanism 40 in this embodiment is connected to a fuel tank FL via a known supply pipe.

[0018] In this embodiment, the peripheral device 10 is a known vehicle-mounted device that is installed in the engine compartment and receives power from the auxiliary battery BT1, and examples of such devices include a radiator fan 10A, a water pump 10B for circulating coolant, or a power steering motor 10C of the electric steering device 8 described below.

[0019] 2, the gas turbine 30 is connected to a load including the driving power source 21 (electric motor) via the above-described generator 45, converter 22, etc. Therefore, the control device 100 can execute fuel injection control via a fuel supply mechanism 40 equipped with a known fuel injection nozzle in order to achieve a desired target rotation speed of the gas turbine 30. Note that the control device 100 may store a correction map, as shown in, for example, Patent Document 2, and may correct the drive voltage of the fuel supply mechanism 40 based on this correction map so as to achieve the target rotation speed.

[0020] The converter 22 includes a known AC / DC converter that converts DC current into AC current and a known DC / DC converter that adjusts the voltage of DC current to a desired voltage. Therefore, the electric power generated by the gas turbine 30 and the generator 45 can be converted via the converter 22 and then stored in, for example, a secondary battery 50 or supplied to the driving power source 21.

[0021] The gas turbine engine vehicle GTV of this embodiment also includes the above-mentioned driving force source 21, electric steering device 8, and brake devices 4LF, 4RF, 4LR, and 4RR (hereinafter collectively referred to as "brake device 4" unless a distinction is required), as equipment used for driving control. The front-wheel drive shaft 2F is provided with the electric steering device 8. The electric steering device 8 includes an electric motor and a gear mechanism (not shown), and is controlled by the vehicle drive control device 20 to adjust the steering angles of the left front wheel 3LF and the right front wheel 3RF.

[0022] The vehicle drive control device 20 includes one or more known electronic control units (ECUs) that control the drive of a drive force source 21 that outputs drive torque for the gas turbine engine vehicle GTV, a steering wheel 9, an electric steering device 8 that controls the steering angle of the steering wheels, and a brake device 4 that controls the braking force of the gas turbine engine vehicle GTV. The vehicle drive control device 20 may also have a function of controlling the drive of a transmission that changes the speed of the output from the drive force source 21 and transmits it to the wheels 3. The vehicle drive control device 20 of this embodiment may also be configured as an electronic control device integrated with a control device 100, which will be described later.

[0023] The control device 100 is configured to include one or more processors (CPUs (Central Processing Units)) and one or more memories communicatively connected to the one or more processors. The control device 100 may be configured to be connectable to a known external network NT such as the Internet via a known communication device CD that can be mounted on a vehicle.

[0024] The control device 100 of this embodiment is configured to have a function of controlling a gas turbine 30 including an impeller 31b provided at an intake port 31a and a turbine 32 arranged downstream of the impeller 31b. The control device 100 of this embodiment is also configured to have a function of PID control of the fuel injection amount in the above-mentioned fuel supply mechanism 40. The control device 100 is electrically connected to the above-mentioned communication device CD, sensors SR, known storage device MD such as a hard disk, and presentation device PD including known in-vehicle speakers SP and display DP, either directly or via communication means such as a controller area network (CAN) or local internet (LIN).

[0025] The sensors SR of this embodiment are a rotation speed sensor SR １ , current sensor SR ２ , and voltage sensor SR ３ Including the rotation speed sensor SR １An example of the current sensor SR is a known rotation speed sensor that has a function of detecting the rotation speed of a gas turbine engine. ２ The voltage sensor SR may be a known current sensor having a function of measuring the value of the input current input to the fuel supply mechanism 40. ３ An example of the sensors SR is a known current sensor that has a function of measuring the value of the drive voltage in the above-mentioned fuel supply mechanism 40. In addition to the above-mentioned sensors, other examples of the sensors SR include various known in-vehicle sensors such as an acceleration sensor and an angular velocity sensor.

[0026] <Detailed Configuration of Gas Turbine Engine> Next, a gas turbine engine of this embodiment including a gas turbine 30 and a fuel supply mechanism 40 will be described with reference to Fig. 3. As shown in the figure, the gas turbine 30 includes a compressor 31 having an intake port 31a, a turbine 32 arranged downstream of a combustor 35, a drive shaft 33 connecting the compressor 31 and the turbine 32, an output shaft 34 arranged coaxially with the turbine 32, and the combustor 35 arranged downstream of the compressor 31.

[0027] The compressor 31 is configured to take in outside air (air) through an air intake port 31a capable of taking in air, and compress the taken-in air via an impeller 31b. The turbine 32 is configured to include a rotor 32a connected to a drive shaft 33 connected to the above-mentioned impeller 31b. The rotor 32a can be started by a known starter motor such as a three-phase AC motor (not shown). At this time, since the rotor 32a is connected to the impeller 31b via the drive shaft 33, the impeller 31b can also rotate in synchronization with the driving of the rotor 32a. The gas turbine 30 of this embodiment is equipped with the above-mentioned rotation speed sensor SR capable of detecting the rotation speed of the rotor 32a. １ is provided.

[0028] The fuel supply mechanism 40 is configured to have a function of injecting fuel supplied from a fuel tank FL into compressed air via a fuel injection nozzle installed in the combustor 35 under the control of the control device 100. As an example, the fuel supply mechanism 40 of the present embodiment can be driven by known PWM (Pulse Width Modulation) control via the control device 100. In the gas turbine 30 configured as described above, when the drive shaft 33 including the rotor 32 a and the impeller 31 b is started (rotated) by the starter motor under the control of the control device 100, the air taken in by the compressor 31 is compressed by the rotation of the impeller 31 b and supplied to the combustor 35.

[0029] At this time, the control device 100 adjusts the amount of fuel injected into the compressed air in the combustor 35 by adjusting the fuel injection amount via the fuel supply valve in the fuel supply mechanism 40. As a result, high-speed gas generated by the combustion is supplied to the turbine 32. This high-speed gas rotates the rotor 32a in the turbine 32, and the driving force (rotation) is transmitted to the generator 45 via the output shaft 34, thereby generating the desired electricity. In addition, the control device 100 detects the rotation speed of the generator 45 via the rotation speed sensor SR. １ Based on the detected value, the amount of fuel injected via the fuel supply mechanism 40 can be adjusted so that the rotor 32a rotates at a desired speed.

[0030] 4 and 5 , a control device 100 capable of controlling the fuel injection amount of the gas turbine engine according to this embodiment will be described. That is, as described above, a predetermined amount of fuel is injected into the combustor 35 of the gas turbine engine via the fuel supply mechanism 40 in accordance with the rotation speed of the rotor 32 a of the turbine 32. As disclosed in the above-mentioned patent document, the control device 100 adjusts the fuel injection amount to the combustor 35 by PID control of the drive voltage of the fuel supply mechanism 40, and controls the rotation speed of the rotor 32 a of the gas turbine 30 to a desired value (target rotation speed).

[0031] At this time, the fuel supply mechanism 40 receives the necessary power from the auxiliary battery BT1, but an inrush current may occur in the peripheral device 10 that also receives power from the auxiliary battery BT1, for example, during startup. If an inrush current occurs in the peripheral device 10 that receives power from the auxiliary battery BT1, this inrush current causes a sudden change in the power (input current and voltage) supplied from the auxiliary battery BT1 to the fuel supply mechanism 40. In this embodiment, a change in the input current and voltage from the auxiliary battery BT1 to the fuel supply mechanism 40 that is caused by an inrush current generated in another peripheral device 10 that shares a power source with the fuel supply mechanism 40 is defined as an "sudden change."

[0032] 6, if such a sudden change occurs in fuel supply mechanism 40, the drive voltage will change significantly, making it difficult to quickly suppress variations in the amount of fuel injected from the fuel injection nozzles using only the PID control by control device 100. In response to this, control device 100 of the present embodiment measures the input current input to fuel supply mechanism 40, and when the drive voltage of fuel supply mechanism 40 fluctuates due to a sudden change in this input current, executes control to temporarily increase the gain of the PID control that controls fuel supply mechanism 40 relative to the basic constant.

[0033] 4, the control device 100 of this embodiment includes a rotation speed measurement unit 101, a power supply parameter measurement unit 102, a PID gain adjustment unit 103, a PID control unit 104, and a display control unit 105. Each of these units is configured as a function executed by the control device 100 of this embodiment.

[0034] The rotation speed measurement unit 101 includes the above-mentioned rotation speed sensor SR １ In this embodiment, the rotation speed of the rotor 32a is detected through the rotation speed sensor SR. １ The rotation speed of the impeller 31b of the gas turbine engine may be detected.

[0035] The power supply parameter measuring unit 102 is the current sensor SR ２ The power supply parameter measuring unit 102 of this embodiment is configured to have a function of measuring the value of the input current input from the auxiliary battery BT1 to the fuel supply mechanism 40 via the voltage sensor SR. ３ , and has a function of measuring the drive voltage of the fuel supply mechanism 40 via the

[0036] The PID gain adjustment unit 103 is configured to have a function of adjusting the gain in the above-described PID control performed by the control device 100. As shown in Fig. 5, the PID gain adjustment unit 103 can adjust the value of the gain Kp in the P (proportional) control of the PID control. The PID gain adjustment unit 103 can also adjust the value of the gain Ki in the I (integral) control of the PID control. Furthermore, the PID gain adjustment unit 103 can adjust the value of the gain Kd in the D (differential) control of the PID control.

[0037] The PID control unit 104 is configured to have a function of PID control of a duty value (duty command value) used in PWM (Pulse Width Modulation) control for driving the fuel supply mechanism 40. More specifically, as shown in FIG. 5 , the PID control unit 104 includes a P control unit 104pc capable of performing known proportional control, an I control unit 104ic capable of performing known integral control, and a D control unit 104dc capable of performing known differential control. The gains (Kp, Ki, and kd) used in the PID control performed by the PID control unit 104 are set using basic constants calculated in advance through experiments or simulations. This allows the PID control unit 104 to PID-control the duty command value of the fuel supply mechanism 40 to inject a desired amount of fuel from the fuel injection nozzle. As described above, the PID control unit 104 of this embodiment PID controls the on-time width (Duty) in the PWM control as the instruction value of the controlled object, but it may also PID control the value of the drive voltage of the fuel supply mechanism 40 itself as the control instruction value.

[0038] The presentation control unit 12 executes a process of presenting various information, such as the operating state of the gas turbine engine including the gas turbine 30, via a presentation device PD including a known in-vehicle speaker SP and display DP. The presentation control unit 12 may present the various information to the occupant via the presentation device PD mounted in the vehicle, or may perform control to access and present the information on an external terminal such as a smartphone carried by the occupant.

[0039] <Gas Turbine Engine Control Method> Next, a gas turbine engine control method that can be executed by the control device 100 of this embodiment will be described with reference to Figures 5 to 7. The gas turbine engine control method may be used as an algorithm of a computer-readable program. A program having such an algorithm may be distributed, for example, via a known network so that it can be downloaded to a gas turbine engine vehicle GTV, or may be distributed in the form of being stored on a recording medium.

[0040] The following description will be given taking, as an example, a case where a user gets into a gas turbine engine vehicle GTV, starts the system, and starts driving. As shown in Figure 7, first, in step 1, the control device 100 detects whether the gas turbine engine, including the gas turbine 30, has started, for example, in response to a power generation demand inside the gas turbine engine vehicle. If the gas turbine engine has not started in step 1, it is determined in step 7, described below, whether the system has been turned off. If the system has not been turned off, the process returns to step 1 and is repeated.

[0041] If it is determined in step 1 that the gas turbine engine has started, the control device 100 detects in the following step 2 whether the gas turbine engine has stably operated. The criterion for determining whether the gas turbine engine has stably operated may be, for example, whether the rotation speed of the rotor 32a is within a predetermined range (e.g., tens of thousands of rpm or more). The rotation speed required for such stable operation may be determined in advance through experiments or simulations depending on the size and rated output of the gas turbine engine. As an example, in this embodiment, the criterion for determination in step 2 is whether the rotation speed of the rotor 32a of the gas turbine 30 exceeds 10,000 rpm due to the starter motor starting described above.

[0042] If the determination condition is not met for some reason in step 2 (No in step 2), the process proceeds to step 1, where the same processing as described above is executed. On the other hand, if the determination condition is met in step 2 and the turbine engine is operating stably (Yes in step 2), the process proceeds to step 3, where it is determined whether the fluctuation in the drive voltage in the fuel supply mechanism 40 has reached a predetermined value or more.

[0043] That is, as shown in Fig. 6, fuel supply mechanism 40 is PID controlled so as to be driven at drive voltage V1 via accessory battery BT1. As an example, in this embodiment, a 12V accessory battery BT1 is used, and therefore control device 100 PID controls the drive voltage of fuel supply mechanism 40 so that the drive voltage is V1 (12V). At this time, as shown in Fig. 5, if an inrush current occurs due to the startup of peripheral device 10, a sudden change UEC occurs in the input current from accessory battery BT1 to fuel supply mechanism 40, which causes a fluctuation in the drive voltage of fuel supply mechanism 40.

[0044] Therefore, in step 3, the control device 100 detects, for example, the voltage sensor SR ３6, the control device 100 may set an appropriate range AR within 10% of the target value V1 (12 V in this example) of the controlled object (the drive voltage). If the drive voltage of the fuel supply mechanism 40 falls outside the appropriate range AR, the control device 100 determines in step 3 that the drive voltage fluctuation is equal to or greater than the predetermined value. In this example, the appropriate range AR is set to a fluctuation range within 10% of the target value, but the appropriate range AR may also be calculated through experiments or simulations.

[0045] If it is determined in step 3 that the fluctuation in the drive voltage in the fuel supply mechanism 40 is equal to or greater than the predetermined value, the control device 100 executes the gain adjustment process of the PID control described above in the following step 4. More specifically, the PID gain adjustment unit 103 of the control device 100 executes a process of increasing the value of the gain Kp used in the P control unit 104pc, while maintaining the values ​​of the gains Ki and Kd in the I control unit 104ic and the D control unit 104dc.

[0046] In this way, the control device 100 executes control of temporarily increasing the gain (Kp) in proportional control of PID control. The rate of increase in the gain Kp by the PID gain adjustment unit 103 can be specified in advance by experiment or simulation. As an example, in step 4, the PID gain adjustment unit 103 executes control of temporarily increasing the value of Kp by 10% of the basic constant (initial setting value).

[0047] Next, in step 5, the control device 100 determines whether the drive voltage of the fuel supply mechanism 40 has returned to a predetermined level. As an example of the predetermined level, the control device 100 may determine whether the drive voltage is within the above-mentioned appropriate range AR. Furthermore, in step 5, instead of detecting whether the drive voltage has returned to the predetermined level, the control device 100 may determine whether a predetermined time has elapsed since the gain adjustment in step 4 was performed. Note that the specific value of the above-mentioned "predetermined time" can be determined in advance by experiment or simulation.

[0048] If the drive voltage is not within the appropriate range AR in step 5 or the predetermined time has not elapsed (No in step 5), the process returns to step 4 and is repeated. On the other hand, if the drive voltage is within the appropriate range AR in step 5 or the predetermined time has elapsed (Yes in step 5), the control device 100 executes a process in the following step 6 to return the temporarily increased value of gain Kp to the basic constant.

[0049] In this way, the control device 100 can execute control to cancel this temporary increase in gain and return the gain value to the basic constant based on either the degree of recovery in the drive voltage described above or the elapsed time since the control to temporarily increase the gain Kp described above was started.

[0050] 6 , the above-described sudden change occurs at time t1, and at time t2, the drive voltage V of the fuel supply mechanism 40 falls outside the appropriate range AR, causing the drive voltage to fluctuate by a predetermined value or more. However, during the period α from time t2 to time t3, the value of the gain Kp described above is temporarily increased from the basic constant. That is, during the period α, the control device 100 is able to execute PID control with the value of Kp temporarily increased. This allows the gain Kp in the P control to be temporarily increased to quickly follow the above-described sudden change, thereby enabling stable operation of the fuel supply mechanism 40.

[0051] According to the gas turbine control method of the present embodiment described above, when a sudden change in the drive voltage occurs in the fuel supply mechanism 40, the gain in the PID control is temporarily increased to improve the ability to follow the fluctuation and suppress variations in the fuel injection amount in the fuel supply mechanism 40, thereby making it possible to quickly return the drive voltage to within the appropriate range AR.

[0052] In step 4, the control device 100 may vary the amount of increase in the gain Kp by which the gain is temporarily increased based on the degree of fluctuation in the drive voltage of the fuel supply mechanism 40. More specifically, for example, the fluctuation range of the drive voltage of the fuel supply mechanism 40 due to the sudden change UEC may be divided into several stages, and the amount of increase in the gain Kp by which the gain is temporarily increased may be set to be larger as the fluctuation range increases according to the stage. This further improves the ability to follow fluctuations caused by the sudden change, making it possible to quickly return the drive voltage of the fuel supply mechanism 40 to within the appropriate range AR.

[0053] <Computer Program, Recording Medium> The computer program that realizes each function of the above-mentioned determination device is a computer program applied to a control device that controls a gas turbine engine equipped with a fuel supply mechanism that injects fuel into compressed air, and can cause one or more processors to execute processing including measuring an input current input to the fuel supply mechanism, and temporarily increasing, with respect to a basic constant, the gain of the PID control that controls the fuel supply mechanism when the drive voltage of the fuel supply mechanism fluctuates due to a sudden change in this input current.

[0054] Furthermore, the computer program that realizes each function of the control device can further execute the following in the above algorithm: (α) execute control to temporarily increase the gain Kp in the proportional control among the gains of the above PID control; (β) cancel this temporary increase in gain and return the gain value to the basic constant based on either the degree of recovery in the above drive voltage or the elapsed time since the start of the control to temporarily increase the gain Kp; and (c) vary the amount of increase in the temporarily increased gain Kp based on the degree of fluctuation in the above drive voltage.

[0055] Furthermore, such a computer program may be stored in, for example, a known recording medium as described above, or may be downloaded from a known server such as a cloud to the gas turbine engine vehicle GTV via a communication device CD.

[0056] Although the preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, the technology of the present disclosure is not limited to such examples. It is clear that a person skilled in the art of the technology to which the present disclosure pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure.
