- Abstract
- This paper provides a technical review of speed control using variable gain PI algorithm for BLDC(Brushless DC) motor. Usually the PI control is used in many motor applications but a general PI control has problems of overshooting and disturbance for response. By the change of PI gain in motor control operation these problems can be solved. To find the optimized PI gains for BLDC motor control many control methods have been proposed. In this paper the control algorithm with a variable PI gain is applied to improve overshooting response in transient region and rapid load disturbance rejection. Fixed gain and variable gain PI controls are compared. The validity of the propose method is verified by experiment.
