Paper Abstract

To enhance the performance of asynchronous motor, and conquer the limitation of the traditional speed-identifier, this paper proposes a speed-identifier direct torque control system. According to transformed form of a mathematical model of asynchronous motor, the system uses the easily-measured motor stator voltage and current and the neural network technique to design a speed-identifier. It can realize speed-sensorless closed loop control. The simulating experiment results of the system show that the speed regulating system has good steady-state performance and dynamic performance, the design is reasonable and effective.
