【Abstract】 An adaptive pseudoreduced-order flux observer for speed sensorless field-oriented control was presented. The feedback gain matrix was obtained through the Popov,and the unstable question which is based on the traditional pole assignment method was overcome. The motor can run stably from low speed to high speed. The experiments verify that the proposed method is feasible.更多还原
