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

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.
