Abstract
Recently, many important results have been established for solving the following problem in linear system theory: Design a dynamic output fe edback compensator such that the gain of the closed-loop transfer func tion is minimized over all frequencies. This paper considers disturban ce attenuation and H-infinity optimization with linear static output f eedback control. Under certain minimum phase assumption on the open-lo op plant and the condition that the open-loop system is stabilizable u sing high gain feedback, the achievable disturbance attenuation level with constraint linear static output feedback is obtained. A synthesis procedure to achieve prespecified disturbance attenuation is develope d and illustrated by means of an example.
