Problems solved by technology
However, the controller designed by the first method is very complex. Due to the limited development of existing airborne sensors and data bus technology, it is difficult to realize high-order complex controllers.
The second design method does not take into account the coupling between the aircraft and the engine
The third method is a purely mathematical method, which has a large computational overhead and is suitable for low-level systems
The fourth method is complex in design and has a large amount of calculation

Embodiment Construction
[0022] The invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 , the control system is mainly composed of a data processing unit and a control unit. When working, the data processing unit receives data from the attitude sensor, barometer, pitot, speed sensor, temperature sensor and pressure sensor through the CAN bus, and receives command signals through the IIC bus, and then the data processing unit performs calculations on it, And optimize the allocation of aircraft and engine control commands. Then the control information is transmitted to the control unit through the IIC bus, and the control unit calculates the control law according to the control information, and then transmits the control signal to the steering gear, so as to control the flight / push of the aircraft.
[0024] The data processing unit is connected with the attitude sensor, barometer, pitot sensor, rotational speed sensor, temperatur...

The invention discloses a flight-thrust comprehensive control system with an improved structure, and belongs to the technical field of flight-thrust comprehensive control. The control system is mainly composed of a data processing unit and a control unit. When the system works, the data processing unit receives, processes and solves sensor data and airplane instructions, conducts allocation optimization on airplane and engine control instructions and then transmits control information to the control unit through a serial port, and the control unit conducts control law solving according to the control information and then transmits control signals to a steering engine. The system is low in cost, reliable in performance and good in control effect and has the good practical value on follow-up development of flight-thrust comprehensive control.
Description
technical field [0001] The invention relates to a flight / thrust integrated control system with an improved structure, belonging to the technical field of flight / thrust integrated control. Background technique [0002] With the continuous improvement of modern aircraft mission requirements, the multi-tasking and multi-function requirements of the aircraft make the complexity of each subsystem of the aircraft continue to increase, which makes the pilot who acts as the coordinator in the traditional design thinking unable to do the job. However, if the flight / push integrated control technology is adopted, the performance of the aircraft can be maximized, the maneuverability and survivability can be improved, the human-machine interface can be simplified, and the workload of the pilot can be reduced. Therefore, the flight / push integrated control technology is widely used in civil and military applications, and has great application prospects. [0003] At present, there are four...
