Problems solved by technology

However, the current aero-engine hardware-in-the-loop simulation test is not fast and versatile because it does not combine automatic code generation technology and model packaging technology. Many problems related to code execution and real-time performance, and most of the existing hardware-in-the-loop simulation methods are aimed at specific systems, have poor portability, have not yet formed a fast development method, and are inefficient

Abstract

The invention discloses a real-time simulation method for an aero-engine control system, belonging to the technical field of simulation applications of aero-engine control systems. The method comprises the steps of first building an aero-engine control system model to achieve pure digital simulation of the control system; second, splitting a controller portion and an engine model portion in the control system, and converting a control algorithm and a model into real-time applications through automatic code generation technology and model packaging technology to run in a real-time system, thusforming a controller simulator and a model simulator; third, completing communication connection between the controller simulator and the model simulator through a reflective memory to realize real-time simulation of an engine control loop, and uploading, by the engine simulator and the controller simulator, running results thereof to respective monitoring upper computers; and finally, observing,by a tester, real-time simulation effects by monitoring the upper computers, and directly adjusting parameters of a controller on line according to the performance indicators of the control system, until the system meets the performance indicator requirements.

Description

technical field [0001] The invention provides a real-time simulation method of an aero-engine control system, which is mainly applied to the technical field of control system simulation. Background technique [0002] Due to its complex structure, large aerodynamic parameters and wide flight envelope, the development of aero-engine's control system is a very complicated process. In the simulation test link, most of the traditional aero-engine control systems are developed using real engines for bench test tests. After problems are found, the controller structure or parameters are re-modified and tested again to make the control system meet the design requirements. However, the repeated testing process using a real engine is cumbersome, costly and low in R&D efficiency, and the design of high-performance aero-engines is becoming more and more complex, which is also a big challenge to the testing and implementation of the control system. In this case, it is undoubtedly the bes...
