基于动态系数法的微型涡喷发动机实时建模
Research on MTE Real-time Modeling Based on Dynamic Coefficient Method
摘要
Abstract
This paper obtained a series of rotating speed-fuel consumption steady state and dynamic property of the engine at some steady points by using system identification method of time domain, obtained steady state relationship and acceleration coefficient for full range by using interpolation method,and established real-time model of the engine for full range by using dynamic coefficient method.This model was characterized by simple structure,small calculating amount,high real-time control.Simulation results show that this model can well reflect the steady state and dynamic property of MTE,compared to experimental data,steady point’s deviation of the model is less than 1%,devia-tion of transient process is less than 6%,which can apply to fault-tolerant control of MTE.关键词
