【Abstract】 The focus of this paper is on stability analysis and control of robust in delta operator uncertain system which is restricted by pole assignment in a circular region. A necessary and sufficient condition of robust D-stability is presented using linear matrix inequalities. Based on which, a necessary and sufficient condition for the existence of controllers is derived and the analytic expression of expected controllers is proposed .The proposed method unifies some previous related results of continuous and discrete systems into the delta frame.更多还原
