连续广义系统时域H_∞鲁棒控制

H_∞ Robust Control for Continuous Descriptor Systems

研究广义系统H∞鲁棒控制问题.首先将参数不确定的广义系统H∞问题转化成只含有一个数值参数的广义系统的H∞问题,然后利用文献中广义系统H∞问题的解,给出参数不确定的广义系统H∞,输出反馈控制器存在的充分条件,并给出控制器的构造形式.

We mainly discuss the robust \%H\%∞ control problem for descriptor systems. We change the robust \%H\%∞ control problem for uncertain descriptor systems to standard \%H\%∞ control problem for descriptor systems. Using the result of reference, a sufficient condition for the existence of \%H\%∞ output feedback controller for the uncertain descriptor systems is presented and a controller is constructed.
