Rapid prototyping simulation method of aircraft engine control system

Abstract

The invention discloses a rapid prototyping simulation method of an aircraft engine control system and belongs to the technical field of design of aircraft engine control systems. First, a control algorithm model is established, the prototype design of the control system is performed through the virtual instrument technology and a real-time hardware platform, the designed aircraft engine control algorithm model is compiled through the automatic code generation technology and downloaded to the real-time hardware platform, and a control algorithm prototype is established rapidly; second, the rapid control prototype is responsible for collecting output signals of an engine simulator after the engine simulator passes through a signal interface unit, relevant control quantities of an engine are calculated according to control instructions and sent to the engine simulator, and the closed loop control over the engine is achieved; finally, a control system designer observes the control effect in real time through a monitoring computer, keeps modifying the control algorithm model according to the requirements of the designer for performance of the control system and repeats the closed loop simulation process of the rapid control prototype till the requirements of the control system designer are met.

Description

technical field [0001] The invention relates to a rapid prototyping method for an aero-engine control system, which is applied to the design simulation of an aero-engine control algorithm and belongs to the field of aero-engine control systems. Background technique [0002] The structure of the engine is complex, and the working conditions are harsh 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 not only needs to 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 margin and give full play to its performance benefits. With the continuous improvement of aero-engine performance requirements, the complexity of aero-engine control systems is increasing. However, the current domestic aero-...
