Abstract

The design of microprocessor based slip power recovery controlled slip ring induction motor is described. The Intel-8085 microprocessor is used to implement speed and current controllers and to generate firing pulses. The motor converter system is modeled in z-domain by using small perturbation around the operating point and the transfer function of the system is obtained. The stability of the system is studied by using Jury´s stability criterion and the design of current and speed controllers is carried out for the good dynamic response. The effects of controller parameters on the dynamic response of the system are studied.
