Self-Control is the simplest and most popular control technique of PM Synchronous motor. However, the variation of instantaneous torque within a switching period of the inverter is one of the main limitations of this technique. Field oriented control and direct torque control are the best techniques for controlling the instantaneous torque of a PM Synchronous motor. However, these techniques are relatively complex compared to self-control and costly resources are required to implement these techniques. In this work a modified self-control method is developed by using rotor position directed Space Vector pulse width Modulation technique. The developed technique reduces the torque angle variation to 1° within a switching period of the inverter. This in turns considerable reduces the instantaneous torque variation of the motor. The torque response and dynamic performance of the developed drive is better than self-control technique and comparable to Field oriented control or Direct torque control technique. However, the developed technique is relatively simple and cost-effective than the Direct torque control or Field oriented control technique. An experimental prototype is developed and satisfactory results are found.
