Abstract: The design problem of H∞ guaranteed cost controller for a class of uncertain systems with poles placed in a special disk is discussed.The controller guarantees the poles of the closed-loop system placed in a special disk and the H∞-bounded constraint on attenuation disturbances,and the system provides a guaranteed cost.The H∞ guaranteed cost controller can be obtained via LMIs.Finally,an example is given to illustrate the effectiveness and feasibility of the theory.
