Usage of Glycerin as an Engine Coolant and Experimental Investigation on Single Cylinder Diesel Engine

Abstract: Among AC drives permanent magnet synchronous motor drives, have been widely used in the field of high performance due to its advantageous features. For electric drives good dynamic response is mandatory for the sudden variations in machine parameters .This work presents a simple and robust speed control scheme of Permanent Magnet Synchronous Motor (PMSM). It is to achieve accurate control performance in the presence of load torque and plant parameter variation.Vector control scheme is used to simplify the PMSM drive. .Kalman Observer is used for estimating the speed of the motor. Space vector pulse width modulation (SVPWM) technique is employed to obtain the required output voltage in the line side of the inverter. Simulation results clearly show that the proposed control scheme can track the speed reference signal successfully under parameter uncertainties and load torque disturbance.
