The most commonly used controller for the speed control of motor is Proportional-Integral (P-I) controller. However, the P-I controller has some disadvantages such as: the high starting overshoot, sensitivity to controller gains and sluggish response due to sudden disturbance. So, the relatively new Integral-Proportional (I-P) controller is proposed to overcome the disadvantages of the P-I controller and the performance these controllers are compared with P, I, P-I and I-P controllers. Simulation results are presented and analyzed for all the controllers. It is observed that I-P controllers give better responses than the traditional P-I for the speed control of BLDC motor drives.
