【Abstract】 A new direct torque control method of asynchronous motor based on space vector modulation is put forward. With thismethod, the stator voltage applied in next control cycle is calculated through stator flux linkage error and torque error so that a dynamicdecoupling control is realized. And the switching control signal of inverter is realized by space vector modulation.Simulation resultsvalidate that it’s efficient and correct.更多还原
