Design and compensation of DC chopper for speed control in DC motor using PLL controller

Abstract

In this paper describes the speed output of DC motor. The DC motor is controlled by DC converter which is using the PLL controller. This proposed is designed and implemented the current output of the DC-DC chopper which fed to DC motor based on close-loop control. The close-loop control is obtained the small signal from the tachogenerator and encoder. The encoder is converted the small signal to similar PWM waveform feedback to PLL detector that is adjusted the PWM signal driven into DC chopper. In order control to applied high precision speed of DC motor.
