Angular Position Control of Brushless DC Motor Using Cuckoo Search algorithm Optimized PD Controller

Controlling the angular position of brushless DC (BLDC) motor is an essential task to improve the transient and the steady state performances under loaded condition. Many problems in BLDC controlling, one of them is the overshoot so that the angular position control of BLDC motor using cuckoo search algorithm optimized proportional derivative (PD) controller to form what the so-called the cuckoo-PD (Cuckoo-PD) controller is proposed in this paper. Control system is realized in a microcontroller namely a 16MHz Atmega 2560 with an absolute encoder as a position sensor. The effectiveness of the Cuckoo-PD controller is tested under constant and varying step functions with the Ziegler-Nichols-PD (ZN-PD) controller as a benchmark. Experimental results show that the Cuckoo-PD controller has slower speed than the ZN-PD controller, but the latter has overshoot and small oscillations during its steady state condition as a consequent of having a fast rise time.
