MRAS的H_∞优化鲁棒设计方法

AN H_∞ OPTIMAL ROBUST DESIGN METHOD FOR MRAS

针对对象状态可测,对象存在扰动的系统,本文提出满足‖H_e(s)‖_∞≤μ及稳定性要求的具有比例积分型自适应律的模型参考自适应控制系统(MRAS)的H_∞优化鲁棒设计方法。该方法所设计出来的系统的稳定性及动态性能好,鲁捧性强。

For a system whose state is observable and disturbances exist,this paper proposes an H_∞ optimal robust design method for MRAS which has PI adaptive law,satisfying || H_e(s) ||_∞≤μ and stability demand,The system designed with this method has good stability,good dynamic performance and strong robustness.
