Optimal PID Control of a BLDC Motor Using Teaching Learning Based Optimization Algorithm

ABSTRACT Due to the increasing gain in importance of the BLDC motor in industrial and home appliances made its effective control much important to meet the requirements of efficient performance. The PID controller finds its applicability in industries and control of different plants for which its parameters are to be tuned effectively. This paper presents TLBO for determining the optimal parameters of a PID controller for controlling and improving performance of a BLDC motor. TLBO algorithm is used to tune the PID Controller and obtain optimal parameters. TLBO is a population based algorithm. It is inspired by the influence of the teaching by the teacher on the students in a class. Due to its attractive characteristics and high efficiency TLBO has been successfully applied to many real world optimization problems. The results obtained from TLBO based controller show significant improvement in performance of BLDC than the existing methods.
