Four quadrant close loop speed control of DC motor

This paper elucidates Low Cost, High performance Chopper based Four Quadrant close loop control of DC Motor. The drive system realized is applicable to Hybrid Electric Vehicles (HEV's) working in all four quadrants. The drive system has been developed and modeled using Scilab /XCOS. The objective of simulation is to predict the performance of the drive system under realistic operating conditions. Close loop speed control of Chopper fed Separately Excited DC Motor (SEDC) is obtained using TI's F28069-M launch pad. Experimental results validate the high performance of the control algorithm utilized in the DC Drive system.
