Abstract

The inverter is turned off during the phase-splitter or no-voltage section when the railway vehicle enters coasting condition. After the coasting condition ends, the inverter is turned on and the traction motor is restarted. Since the actual speed is unknown, restart at coasting condition is the key problem for the speed sensorless control of the traction motor. A restart method based on integral sliding mode (ISM) is proposed in this paper. The nonlinear system model based on the rotor back-EMF is built. The integral sliding mode control is designed to estimate the initial speed of induction motor during restart at coasting condition. Meanwhile, a reasonable switching function is designed to alleviate chattering phenomenon. The stability of control system and robustness to the motor rotor time constant are analyzed. Simulations and experiments have verified the proposed method. Compared with the existing input-output linearization method, it is shown that the proposed method has better dynamic performance and great robustness.

Key words： Induction motor speed sensorless control restart at coasting condition integral sliding mode
