Rapid Prototyping Simulation Method for Aeroengine Control System

Abstract

The invention discloses a rapid prototype simulation method for an aero-engine control system, belonging to the technical field of aero-engine control system design. First establish the control algorithm model, use virtual instrument technology and real-time hardware platform to carry out the prototype design of the control system, compile and download the designed aero-engine control algorithm model to the real-time hardware platform through automatic code generation technology, and quickly establish the control algorithm prototype ;Secondly, the rapid control prototype is responsible for collecting the output signal of the engine simulator after passing through the signal interface unit, and calculates the relevant control quantities of the engine according to the control instructions and sends them to the engine simulator to realize the closed-loop control of the engine; finally, the control system The designer observes the control effect in real time by monitoring the computer, continuously modifies the control algorithm model according to the designer's performance requirements for the control system, and repeats the closed-loop simulation process of the rapid control prototype until the control system designer's requirements are met.
