Closed loop controlled PMDC motor drive

This paper deals with the control of speed regulation of a separately excited PMDC motor fed from single phase fully controlled converter. In many industries , the PMDC motor plays a vital role for variety of control applications. The speed regulation of separately excited PMDC motor is poor in discontinuous mode when fed from single phase fully controlled converter. The aim of this work is to implement an efficient controller like PI, PD and PID for PMDC drive operating in discontinuous mode of the converter. In this work it is observed that the PI controller delivers superior performance than any other controller in the discontinuous mode of the converter, in achieving better speed regulation. Simulation results prove the effectiveness of the proposed PI controller compared with other controllers.
