Abstract :
This paper describes a method to achieve precise torque and speed control of AC traction in low speed range. The authors apply an instantaneous speed observer to improve the speed information and propose a new pole assignment by analysis in multirate-discrete-time domain. Validity of this method is verified though various simulations.
