一类不确定采样控制系统鲁棒控制器的设计

The Design of Robust Controller for a Class of Uncertain Sampled-data Control Systems

针对一类不确定采样系统进行了鲁棒控制器的设计，给出采样系统的最优鲁棒控制 器及其存在的充分条件，并将该充分条件转化为一类极大极小的优化命题，在此基础上求出系 统具有最小增益的最优鲁棒制器．从实例的分析中可以看出，系统控制器的增益有较明显的 降低．

The design of robust stability optimal controller for a class of uncertain sam- pled-data systeme is investigated in this paper. The controller and its existing sufficient condition is given, moreover, this condition is transfomed to an equivalent min-max optimization prob- lem. Then a stable controller with minimal gain is determined. From the analysis of the example, the gain of controller dwindles greatly.
