本文对具有实参数摄动和未建模动态不确定性的复合摄动问题的鲁棒性能设计进行了深入研究，首次提出利用H∞控制理论中的混合灵敏度方法处理某些复合摄动问题的鲁棒性能设计．其思路是：首先将复合摄动问题的鲁棒性能设计转化为参数不确定性系统的鲁棒性能设计问题；然后将这种参数不确定性问题变换成标准H∞控制问题结构；最后利用“DGKF”或状态反馈的方法获得问题的解．
In this paper, the robust performance design of complex perturbation problems with real parameter perturbations and unmodeled dynamic uncertainties is studied in depth. The hybrid sensitivity method in H∞ control theory is proposed for the first time to deal with some complex perturbation problems Robust performance design. The idea is: firstly, the robust performance design of the complex perturbation problem is transformed into the robust performance design problem of the parametric uncertainty system; then, the parameter uncertainty problem is transformed into the standard H∞ control problem structure; finally, DGKF "or state feedback method to get the solution of the problem.
