Abstract: Brushless Direct Current (BLDC) motors have several advantages including high efficiency and high speed ranges and accordingly are commonly used in a broad range of industrial applications. To accommodate the high performance requirement of the modern industry, optimization of the proportional-integral (PI) and proportional-integral-derivative (PID) controller parameters are highly explored and several tuning methods have been suggested. This work demonstrates a robust permanent magnet brushless dc motor (PMBLDCM) controller design method where a simulated annealing algorithm is employed to tune the parameters of a PI current controller and a PID speed controller of the motor. Three response performance parameters including overshoot, rise time, and settling time are simultaneously optimized during the tuning process. To enhance the overall performance of the system under wide loading conditions, a set of operating points is considered within the objective function. The technique is compared to both Particle Swarm Optimization and Ziegler-Nichols tuning methods and results show the superiority of the proposed approach.
