MATLAB based Simulations on DC Shunt Motor based Four Quadrant chopper with Driver Circuit

This article describes the DC Shunt motor as an interesting piece to develop a speed and load characteristics. The purpose of this work is to develop a less complex and reduced cost based process to control the speed of DC shunt motors using the most popular technique four-quadrant chopper method. The electric drive systems used in industrial applications are adapted for electrical interconnection higher performance and accuracy demands. The speediness of the DC Shunt Motor is well controlled by PI controller. This motor is fed via a 4-quadrant chopper. A microcontroller handles the command which is completely digitalized. The drive system provides good vigorous output across a varied ranges of speed, comprising zero speed, with best turn-on and off phase angles for operational quadrant. The advantages are Reliable operations at large currents. The proposed dc motor based drive is investigated, modeled and simulated to validate its viability for four-quadrant operation, speed control and the simulation results are presented.
