Abstract

Based on the variable speed variable pitch wind generator for wind energy utilization and the dynamic stability of the high demand characteristics，a linear parameter varying(LPV) system model is established，a sufficient condition of the adaptive robust guaranteed cost controller is presented and a new adaptive guaranteed cost controller(AGCC) is proposed in this paper. First，the uncertain parameters of the system is estimated by using the adaptive method，then the estimated uncertain parameters and robust guaranteed cost control are used design state feedback gain，the feedback gain is obtained by a set of method of linear matrix in equality(LMI) constraints，and the controller can meet a quadratic performance evaluation．The simulation results show that，in terms of low or high wind speed，the controller has good robust interference su¬ppression．
