Abstract

Simplicity and effectiveness of control is required for proper injection of square wave phase current for reducing current ripple. Predictive control is proven technique for accuracy and effectiveness of control and hysteresis control is the simplest control technique among all techniques. Combination of hysteresis and predictive control with stationary plane control gives added advantage and flexibility in control. Combination of hysteresis and predictive control in stationary plane for PM BLDC motor reduces current ripple as well as torque ripple giving higher average torque throughout the speed range then conventional PI control. Result shows the effectiveness of the control technique.
