In order to solve the problems of wind power generation system model uncertainty, we designed a robust tracking controller according to the robust control theories and the method of linear matrix inequality (LMI). For ensuring the stability and dynamic characteristics of robust, we gave the calculating method of proportion and integral gains, researched the robust control strategy with pole constraint that is based on minimal power tracking controller. The results of the simulation show the controller can realize the steady close-loop and possess good disturbance rejection and dynamic characteristic in some disturbances and uncertainties existed in system.
