Nature Inspired Optimization Algorithms to BLDC Motor Drive

The brushless direct current (BLDC) motor is being used in Aerospace, Naval, Military, automation and household appliances due to its advantages such as High efficiency, noiseless operation and wide speed range. The BLDC motor is innately electronic controlled and requires rotor position information for correct commutations of current. The issues with rotor position sensors have motivated research in the demesne of sensorless motor drives. Sensorless control has been an active research motive for the last three decades. The Bio-inspired optimization algorithms such as particle swarm optimization algorithm with several inertia weight strategies(SPSO, CIPSO, and CPSO), Bat algorithm (BA) and Firefly algorithm (FFA)were developed to tune PID controller parameters for the speed control of BLDC motor.
