| Abstract: | A fuzzy controller has been introduce to deal with t he issue by giving different control voltages, which improves the electric torque response of the system and eliminates the torque ripple in steady state. A stato r flux angle mapping method is proposed to reduce the fuzzy rule numbers while k eeping the performance of system satisfactory. To improve the system performance at low speeds, a fuzzy stator resistance estimator is designed to eliminate the error in flux measurement due to the change in stator resistance. The resul ts of the experiment verified the feasibility of the proposed strategy. |
