本文对参数不确定振动系统在随机干扰作用下鲁棒主动控制设计进行了讨论 .提出了在主动控制的基础上 ,综合利用参数优化和鲁棒特征值配置等技术 ,通过调节参数r修改控制律以获得鲁棒控制的设计方法 ,并定义综合指标ε(r)作为确定最优r值的依据 .最后以一例子说明该方法的可行性及有效性 . In this paper, the design of robust active control for parametric uncertain vibration system under stochastic disturbance is discussed. Based on the active control, the optimization of parameters and the robust eigenvalue configuration are combined to modify the control law In order to obtain a robust control design method, and define the comprehensive index ε (r) as the basis for determining the optimal r value.Finally an example is given to illustrate the feasibility and effectiveness of the proposed method.
