摘要/Abstract

摘要： 一种新的滑模变结构控制方法—全程滑态变结构控制首次应用于航空发动机控制系统,该控制方法能有效地缩短系统状态到达滑动模态的时间,避免了定常滑态变结构控制系统在能达阶段对扰动的敏感性,且其控制律的设计可以改善系统的瞬态性能,克服未知参数摄动的影响。仿真结果表明:基于全程滑态变结构控制所设计的发动机控制系统,其鲁棒性要优于发动机定常滑态变结构控制系统。

Abstract: A new variable structure control approach, that is, Global Variable Structure Control(GVSC), was introduced to aeroengine control system. This approach can efficiently shorten the time during which system initial states reach the sliding mode, overcome the sensitivity of Constant Variable Structure Control (CVSC) to disturbance and model parameters variation during this period . Furthermore, The design of its control principle also improves transient performance of the system. On the base of this new theory , aeroengine GVSC regulator was designed. it is shown that aero engine GVSC regulator is more robust than aero engine CVSC regulator . GVSC is a better control scheme for aero engine with uncertainties.
