碩士 === 淡江大學 === 電機工程學系 === 89 === This paper is concerned with the design problem of robust tracking controllers. We investigate the necessary and sufficient conditions under which a linear time-invariant system can maintain internal stability and possess the capability of tracking a step input in the face of system uncertainties. On the synthesis part, one goal of the controller design is to enlarge as big as possible the stability margin of the perturbations in order to increase the robustness of tracking capability of the system. Both of the cases that the nominal system is subject to additive perturbations or multiplicative perturbations are discussed.
