Abstract

The invention discloses a self-adaptive cycle engine embedded control system simulation method and platform, and the method comprises the steps: building a self-adaptive cycle engine neural network dynamic model according to a self-adaptive cycle engine part-level model, and completing the transplantation of a code to an embedded processor; secondly, designing a self-adaptive cycle engine control plan, developing a control algorithm, completing automatic generation of codes and transplanting the codes to an embedded processor; designing a communication mode between the engine simulator and the controller, and developing a communication interface function of an engine model and a control algorithm; and finally, developing a rapid prototype machine to acquire and monitor an analog quantity signal output by the controller, and completing experimental verification. The system overcomes the defects that the previous advanced control system can only be verified at a PC (Personal Computer) end in the initial design stage and cannot simulate noise in actual signal transmission, improves the development efficiency of the control system, reduces the development cost, and has a positive promotion effect on verifying whether the advanced control system can be applied to an aero-engine or not.

Description

technical field [0001] The invention belongs to the field of aero-engine control system simulation platform design, in particular to a simulation method and platform for an adaptive cycle engine embedded control system. Background technique [0002] The structure of the engine is complex and the working state is bad and changeable. The control system of the engine is an effective way to ensure the safe and stable flight of the aircraft. Advanced aero-engines put forward higher requirements for safety, stability and reliability. It should not only make the engine work stably and reliably under changing conditions, meet performance requirements and control functions, but also ensure that the engine has sufficient safety margins and give full play to its performance benefits. With the continuous improvement of aero-engine performance requirements, the aero-engine control system has become more and more complex, but the current domestic aero-engine control system development pr...
