| Abstract: | In the conventional direct torque control system,the stator flux can't be identified accurately because of the change of the stator resistance and the integral calculation,and the speed sensor has its deficiency.This paper deals with these problems.The accurately stator flux of full speed range is acquired by adopting new flux observer,and the motor speed is identified by adopting neural network based on it.At the end,the simulation and experiment results are presented. |
