摘要 通过分析状态参数对系统性能影响程度的大小,提出了状态参数敏感度的概念.根据这一概念可以确定关键的状态参数,从而实现准最优控制.考虑到参数的时变特性,利用模糊技术对参数进行实时在线修正,取得了良好的控制效果.这种方法可以进一步提高振动控制系统的控制品质和鲁棒性. After analyzing the sensitivity of the feedback state parameters individually,the key state parameters can be found,and then the sub-optimal control can be realized,and a good control can be reached.Online optimization for control feedback variables can be realized by using the fuzzy technique,and it can have a better control effort.This method can improve the control quality and robustness of vibration control system.
