[0002] In the aviation industry, aero-engines, as the core of aircraft, directly affect the overall performance and safety of the aircraft. With the rapid development of modern aviation technology, the design and testing processes of aero-engines have become increasingly complex, demanding higher standards for testing environments and precision. While traditional high-altitude simulation testing methods can simulate the impact of the high-altitude environment on engines to some extent, they suffer from limitations such as long testing cycles, high costs, and significant safety risks. Furthermore, existing high-altitude simulation control systems lack convenience, versatility, and real-time performance in high-altitude hardware-in-the-loop simulation testing scenarios. Therefore, exploring a more efficient, safe, and accurate testing method is crucial. Real-time simulation technology, based on computer modeling and numerical calculation, simulates real-world physical processes by establishing high-precision mathematical models, thereby enabling the analysis and optimization of complex systems. In high-altitude simulation testing, real-time simulation technology can simulate the engine's operating state under high-altitude conditions, including changes in parameters such as airflow speed, temperature, and pressure, as well as internal combustion and turbine rotation processes. By acquiring and processing test data in real time, the system can monitor and analyze engine performance, promptly identify potential problems, and implement optimizations. This technology not only significantly improves testing efficiency and accuracy, reduces testing costs and safety risks, but also provides more comprehensive data support for the design and optimization of aero engines.

[0003] In the implementation of high-altitude simulation tests, the key lies in establishing a high-precision mathematical model of the engine and simulating the complex meteorological conditions in the high-altitude environment. This requires in-depth research into the working principles and physical characteristics of aero-engines, considering the impact of various factors on engine performance, such as airflow speed, temperature, pressure, and fuel type. Simultaneously, it necessitates the development of corresponding simulation software and hardware platforms to support real-time data acquisition, processing, and analysis. These software and hardware platforms need to possess high-speed computing capabilities, high-precision data acquisition and processing capabilities, as well as user-friendly interfaces and visualization functions, enabling test personnel to easily monitor and analyze test results. Furthermore, real-time simulation technology can be combined with intelligent control systems to achieve more intelligent aero-engine testing. By introducing artificial intelligence algorithms and machine learning techniques, the system can automatically identify and analyze patterns and trends in test data, predict engine performance changes, and propose corresponding optimization suggestions. This intelligent testing method can not only further improve testing efficiency and accuracy but also provide more comprehensive and in-depth data support for aero-engine research and development and testing, promoting continuous innovation and development in aero-engine technology.

It should be understood that the embodiments shown and described in the drawings are merely exemplary and are intended to illustrate the principles and spirit of the invention, and are not intended to limit the scope of the invention.

[0027] Example 1: This invention provides an intelligent control simulation system for high-altitude simulation experiments, such as... Figure 1 As shown, it includes a linkage test control console, a model simulation platform, a control simulation platform, an action actuator, an operation panel, and a throttle lever. The control simulation platform is communicatively connected to the model simulation platform, the operation panel, and the action actuator, respectively. The linkage test control console is communicatively connected to the control simulation platform, the model simulation platform, and the throttle lever, respectively.

[0028] The linkage test control console is used to deploy the high-altitude simulation control system model, configure the human-machine interface, and store test data. The high-altitude simulation control system model includes a controller model, an engine model, and a test device model.

[0030] The control simulation platform is used to call the controller model from the linkage test control console and receive the initial control commands sent by the model simulation platform. The controller model processes the initial control commands and generates control signals for the action actuator.

[0031] The action executor is used to receive control signals generated by the control simulation platform and perform corresponding actions according to the control signals.

[0032] The control panel is used to simulate and model the on-board control interface and signals, and to provide feedback and manual intervention support for the system control process. The control panel mainly consists of physical components such as switches, buttons, and indicator lights. Through real hardware operation and display, it can physically simulate the output of system operation behaviors and acquire the status of various switch signals in real time, providing intuitive feedback and manual intervention support for the control process, further improving the system's human-machine interface and test operability.

[0037] The host computer for real-time simulation of the model is connected to the throttle lever via a USB interface to receive control commands from the throttle lever in real time.

[0038] In this embodiment of the invention, the model simulation platform is designed with a combination of simulation server and simulation chassis. While ensuring the efficient computing power of the model, it significantly enhances the scalability of the hardware interface, ensuring that the simulation environment of the test device model and engine model is compatible and interchangeable with the hardware board resources of the control simulation platform. This further improves the system's flexibility, scalability and adaptability to various application scenarios.

[0039] like Figure 1 As shown, the model simulation platform includes a Simple real-time simulation server, a model simulation chassis, a model signal conditioning chassis, a model signal testing box, and a model signal adapter unit, which are connected in sequence via communication.

[0040] The Simpole real-time simulation server connects to the real-time simulation host computer via Ethernet, and is used to call and run engine models and test device models from the real-time simulation host computer. It has a built-in reflective memory card and a real-time clock interrupt board, which supports high-precision synchronous control and low-latency data exchange, ensuring the real-time performance and stability of complex system models in multi-platform collaborative simulation.

[0041] In this embodiment of the invention, the high-performance real-time simulation cloud platform upon which the Simple software is based adopts a true symmetric multiprocessor (SMP) architecture, supporting multi-core multi-task scheduling, which can effectively improve simulation computing efficiency. The platform is configured with a real-time clock interrupt card to generate a unified and accurate clock signal, completely eliminating the time drift problem caused by temperature changes due to reliance on the CPU's internal clock. Based on a real-time Linux operating system and triggered by a high-precision clock card, the system can achieve deterministic scheduling delay control, supporting real-time simulation at the 50μs level, with a maximum scheduling delay of less than 10μs.

[0042] The model simulation platform supports multi-model, multi-core parallel computing and real-time interaction. It allows allocation of specific processor cores based on the operational requirements of engine and test device models, and enables independent start / stop and step control for each model. It also supports distributed model deployment, further enhancing system scalability and flexibility. The system meets the performance requirements for converting complex system models into real-time code and downloading it to the real-time Simpole simulation server for real-time solving, ensuring that the overall solution cycle of the Simpole simulation server and the control simulation chassis is controlled within 20ms. The Simpole simulation server and its accompanying simulation monitoring and management software (SimpoleView) together construct an efficient and reliable real-time simulation and management environment.

[0043] The model simulation chassis integrates digital input / output boards, analog output boards, and analog input boards for I / O signal input / output processing of the system model, ensuring high-speed and accurate interaction of simulation data and providing stable signal support for backend equipment and system verification.

[0044] Model signal conditioning chassis are used for characteristic matching and conversion of I / O signals, realizing the conditioning, isolation and protection of analog and digital signals, and improving the compatibility, anti-interference capability and operational safety of the overall signal link.

[0045] The model signal test box is used for bypass monitoring and detection of signals, supports fault simulation and troubleshooting, enhances the system's fault detection and location capabilities, and improves troubleshooting efficiency and system reliability during the debugging and verification phase.

[0046] The model signal adaptation unit serves as the system's wiring and interface management device. It integrates and standardizes all I / O signal resources, converting simulation signals into electrical interface standards consistent with actual products. This enables the system to interface with real-world application scenarios, improving system integration and engineering feasibility.

[0047] In this embodiment of the invention, the control simulation platform is built on a simulation chassis, calls the controller model, and achieves high-speed signal interaction with actual valves, sensors, and other actuators through the simulation I / O interface, issuing control commands and collecting feedback data in real time. This approach enables high-altitude simulated hardware-in-the-loop tests to be conducted in an environment closely resembling real-world working conditions, verifying the effectiveness and robustness of the control algorithm and providing reliable support for subsequent control system optimization and engineering applications.

[0048] like Figure 1 As shown, the control simulation platform includes a control simulation chassis, a control signal conditioning chassis, a control signal testing chassis, and a control signal adapter unit, which are connected in sequence via communication.

[0049] The control simulation chassis connects to the real-time control simulation host computer via Ethernet, and is used to call and run the controller model from the real-time control simulation host computer. It integrates a digital output board, a reflective memory card, an analog output board, and a real-time clock interrupt board, supporting high-precision, low-latency real-time control command calculation and signal output. The control simulation chassis also connects to the Simple real-time simulation server through the reflective memory channel.

[0050] In this embodiment of the invention, the control simulation platform and the model simulation platform remain relatively independent in terms of hardware signal links, avoiding signal coupling and interference problems. The two platforms achieve real-time data synchronization and interaction through reflective memory technology, ensuring low-latency and high-reliability data consistency support during multi-platform parallel simulation. This effectively guarantees the system's real-time performance and simulation accuracy, meeting the stringent requirements of complex high-altitude simulation experiments for system collaborative control and data consistency. Furthermore, reflective memory also supports global shared memory management, high-speed data distribution, and software transparency. During the experiment, even if the number of system nodes increases or a single point of failure occurs, the determinism and stability of data synchronization are still guaranteed, providing solid support for real-time control and data monitoring in high-altitude simulation experiments.

[0051] The control signal conditioning chassis is used to realize the electrical characteristic conversion and signal matching between the digital and analog signal boards of the control simulation platform and external devices, ensuring the stability, reliability and compatibility of system signal transmission.

[0052] The control signal test box is used for bypass testing of digital and analog signals between the actuator and the control simulation platform. It supports manual fault injection and improves the system's reliability and robustness by simulating various abnormal operating conditions to assist in system function verification and fault tolerance testing.

[0053] The control signal adapter unit is connected to the operation panel and the actuator respectively, and is used to realize the standardized connection of digital and analog signals between the operation panel, the actuator and the control simulation platform, ensuring the accuracy of signal interconnection, timing consistency and interface compatibility, and improving system integration efficiency and maintenance convenience.

[0054] In embodiments of the present invention, such as Figure 1 As shown, the actuator includes a hydraulic station assembly, a hydraulic cylinder assembly, and a valve assembly.

[0055] The valve assembly connects to the actual hardware actuator via a semi-physical interface, enabling data interaction between the virtual model and the real equipment.

[0056] The hydraulic station unit is used to provide a stable high-pressure hydraulic oil as a power source.

[0057] Hydraulic cylinder blocks are used to convert hydraulic energy into mechanical motion, driving various mechanisms to complete displacement or adjustment actions.

[0058] Example 2: This invention provides an intelligent control simulation method for high-altitude simulation experiments, implemented based on the intelligent control simulation system for high-altitude simulation experiments described in Embodiment 1. Figure 2 As shown, the process includes the following steps S1 to S7: S1. Configure the wiring and communication for the intelligent control simulation system for high-altitude simulation tests.

[0059] In this embodiment of the invention, the control simulation chassis is connected to the control signal conditioning chassis via I / O signal connection cables that match the interfaces of the digital output boards and analog output boards in the control simulation chassis, thus completing the electrical characteristic conversion of digital and analog signals. The conditioned signal is then transmitted to the control signal test box, facilitating bypass monitoring, detection, and fault injection before signal output. Subsequently, the signal enters the control signal adaptation unit, where it undergoes signal integration and standardization processing before finally connecting to the valve assembly in the actuator. Through this complete signal transmission and control link, the system achieves efficient and reliable interconnection between various components, ensuring accurate issuance of control commands and rapid response from the actuator, thereby effectively supporting the stringent requirements of real-time performance, accuracy, and stability in high-altitude environment simulation experiments.

[0060] In this embodiment of the invention, the model simulation platform and the control simulation platform establish a high-speed data communication link with their respective host computers via Ethernet to achieve real-time data transmission and interaction, supporting the following functions: (1) The host computer can compile the simulation model and download the generated real-time executable file to the simulation platform for running, ensuring the efficiency of model deployment and updates.

[0061] (2) The host computer can adjust the parameters of the model running on the simulation platform online, support dynamic adjustment and control strategy optimization, and improve the flexibility of debugging and verification.

[0062] (3) The changes of each model variable and parameter in the simulation platform can be synchronized to the host computer monitoring interface in real time to ensure the immediate feedback and intuitive display of data, which facilitates real-time status monitoring, performance analysis and fault diagnosis.

[0063] Through the above functions, the model simulation platform and the control simulation platform realize a closed-loop working mode integrating development, debugging, and monitoring, which greatly improves the system simulation efficiency and the convenience and reliability of engineering applications.

[0064] In this embodiment of the invention, to meet the system's requirement for highly real-time data interaction, a communication method based on Reflective Memory (RFM) is adopted. In the system, the control simulation platform and the model simulation platform are connected to their respective host computers via Ethernet to realize model compilation, downloading, online debugging, and real-time monitoring. Simultaneously, the two simulation platforms maintain relative independence in their hardware signal links, establishing a high-speed data synchronization channel through a reflective memory switch.

[0065] During the experiment, after data is written from the control simulation platform or model simulation platform to the local reflected memory, the system sequentially transmits the data to the next node in the ring network through a high-speed logical synchronization mechanism. Each node, upon receiving the data, immediately writes it to its local backup and continues transmission. Data completes a full cycle of synchronization within microseconds and is automatically cleared upon returning to the starting node, ensuring that each node has a consistent copy of the data at the same memory address. Through this mechanism, the processors of each platform can read the latest shared data locally in real time without accessing an external network, effectively improving data access speed and system responsiveness.

[0066] S2. Construct a high-altitude simulation control system model, and then divide it into a controller model, an engine model, and a test device model. Deploy it to the linkage test control console, and set up a human-machine interface on the linkage test control console.

[0067] In this embodiment of the invention, a high-altitude simulation control system model is built in MATLAB / Simulink software. The controller model, engine model, and test device model are each encapsulated into .tgz files that can run in a real-time environment and deployed to the linkage test control console. Subsequently, the SimpleView system is logged in through a browser, and a simulation task is created using the "Add Project" function. According to the interaction requirements of the real-time simulation interface, the key variables of the controller model, test device model, and engine model are bound to the board resource interface variables developed by the platform to ensure the accuracy and real-time performance of signal exchange between the digital model and the hardware interface. At the same time, necessary variable binding and mapping configurations are performed for the input and output interfaces between different models to support multi-model joint simulation and data flow. By uniformly loading and running each model file, centralized management and efficient scheduling of the entire system model are achieved, ensuring the coordination and stability of the simulation process.

[0068] In this embodiment of the invention, key variables are selected and categorized from the simulation model according to experimental requirements, and configured in a targeted manner to ensure that the monitoring interface layout is intuitive and easy to operate. A dynamic display function for experimental data is designed and implemented, supporting real-time plotting of data curves, intuitive display of variable change trends, and multi-variable comparative analysis capabilities. The system supports customizable monitoring interface layouts, flexibly calling various visualization controls such as tables, curves, and instruments to quickly construct monitoring interfaces that meet different experimental needs. Furthermore, experimental auxiliary setting options are added, such as online parameter adjustment, facilitating dynamic optimization of model behavior during simulation. In addition, the system can synchronously monitor key performance indicators such as model name, CPU allocation number, process number, model running status, simulation running cycle, frame count, timeout count, cumulative running time, average running time, maximum running time, system latency, and maximum latency. SimpleView also supports real-time playback, storage, download, and deletion of simulation data, further improving the data traceability and controllability of the simulation experiment.

[0069] S3. Test the response speed and execution performance of the action executor through the operation panel.

[0070] In this embodiment of the invention, by issuing and monitoring feedback on basic operation commands such as start and stop, the stability, accuracy and consistency of the system under actual operating conditions are evaluated, ensuring that each action mechanism can reliably execute as expected, and providing sufficient functional verification and system guarantee for formal testing.

[0071] S4. The test device model and engine model are called from the linkage test control console through the model simulation platform, the control command of the throttle lever is received, the high-altitude simulated semi-physical simulation test is carried out, and the initial control command is generated.

[0072] The test device model is equipped with sensor models. It receives control commands from the throttle lever through the engine model to simulate the dynamic working conditions of the engine. The test device model controls the analog input and output boards to receive or output current signals, communicate with the actuator, and transmit the working status signals of the real equipment. It receives control commands from the controller model through the sensor models and feeds back the sensor status to conduct high-altitude simulation semi-physical simulation tests.

[0073] Subsequently, based on the preset virtual environment parameters and test conditions, a high-altitude simulated semi-physical simulation test scenario and preliminary parameter calculations were performed on the model simulation platform to generate the corresponding initial control command set. The generated control commands were transmitted to the control simulation platform in real time via a reflective memory channel. Upon receiving the valve angle electrical signal, the system converts the input value into a specific valve opening command according to the set unit conversion rules, driving the actual actuator to perform the action. This completes the closed-loop simulation verification from the digital model to the physical device, ensuring the feasibility and effectiveness of the control strategy in a real-world environment.

[0074] S5. The controller model is called from the linkage test control console through the control simulation platform, and the initial control command sent by the model simulation platform is received. The controller model processes the initial control command and generates the control signal of the action execution body.

[0075] In this embodiment of the invention, after receiving control commands from the model simulation platform, the control simulation platform invokes the controller model, processes real-time data using high-precision algorithms, and outputs current signals to the actuators via analog signal input cards, thereby completing the dynamic control and optimization of the real equipment. Simultaneously, the control simulation platform generates optimized control strategies that better suit the current operating conditions based on real-time feedback and sends these strategies back to the model simulation platform via reflected memory, supporting iterative updates of the control strategies and continuous improvement of system performance.

[0076] S6. Control the actuator to perform corresponding actions according to the control signal, simulate actual operation changes by adjusting the position of the throttle lever, and receive switching instructions sent by the control panel to dynamically adjust the engine test conditions.

[0077] In this embodiment of the invention, the valve action responds to the received control command signal. The hydraulic station, as the main power source, starts to provide stable hydraulic pressure to the hydraulic cylinder. The hydraulic cylinder drives the butterfly valve to adjust its angle, precisely controlling the opening of the airflow channel. The actual rotation angle of the valve is measured by a position sensor, which outputs a 0-5V voltage signal to the control simulation platform. This signal is processed by the control signal conditioning cabinet, converting the 0-5V voltage signal into a 0-20mA current signal to ensure stable and reliable signal transmission. Finally, the converted specific value is transmitted to the model simulation platform through the reflection memory, completing a virtual-real data closed loop and supporting high-precision dynamic control simulation in high-altitude environments.

[0078] During the test, when valve vibration or jitter is detected, the host computer can send commands to the simulation platform in real time to dynamically adjust the control algorithm parameters and optimize the valve control effect. If the expected control requirements still cannot be met after adjustment, a forced stop command can be sent through the control panel to interrupt the test in a timely manner and ensure the safety of system operation. After the valve control effect is good and stable, the switching command sent by the control panel is received through the digital input / output board to adjust the engine test conditions and further verify the stability and adaptability of the control algorithm under different operating conditions.
