摘要

为了对发动机的动态过程进行控制

提出了一种基于SQP的全局寻优控制方法.每一步寻优过程分为长程优化和短程优化两个阶段.根据长程优化结果

重构了关联目标函数

在此基础上

进行了短程优化修正

并利用修正结果进行控制.将这种方法应用于某型航空发动机的过渡态控制中

得到了理想的控制结果.仿真结果表明该方法能较好地解决一般局部优化方法在有纯延迟、模型失配等情况下的优化控制效果下降的问题.

Abstract

A global optimization based on sequential quadratic programming(SQP) is proposed for aero engine control in dynamic process.Optimization process consists of an overall and a component phase.The authors have implemented algorithm which employs the overall optimal results to redesign relating objective functions.Based on this

component optimization has been carried out with the purpose of correction and the result has been used for cycle control.This approach is applied to aero-engine control under transient conditions.As a result

the process is perfect.The simulation showed that this method can solve the problem that the general local optimization is unfeasible for the system with pure delay part and unmatched model.
