【Abstract】 In order to improve tracking precision in steady state, the design method of robust guaranteed cost PI controllers for linear systems was proposed with norm-bounded parameter uncertainties and a given quadratic performance index. A sufficient condition for the existence of guaranteed cost PI controllers is derived and a procedure to determining the PI controller parameters is given in terms of the feasible solutions to a certain linear matrix inequality.更多还原
