Abstract:

This paper presents the comparison of armature voltage control and combined armature voltage and field control of a separately excited dc motor using PI controller. This research paper is a comparison analysis so on comparing the two systems it is found that the efficiency of DC motor is enhanced by controlling both armature voltage and field voltage simultaneously which are decided by PI controller.In this paper power electronics converter (BUCK CHOPPER) are utilized to control armature voltage and field voltage simultaniously.GTO is used as a power electronics switch in this paper.The MATLAB simulation of armature voltage control and combined armature and field voltage control are compared and the simulation results of speed and enhancement of efficiency are also analyzed in this paper.

Keywords:

separately excited dc motor, speed control of DC motors, PI controller, hysteresis current controller, Efficiency enhancement.
