Abstract
In BLDC motor, difference in current deviation of entering and leaving phase at the time of commutation causes torque ripple resulting in vibration and noise which restricts them to use for certain applications. This paper presents a simple controller based on bio-inspired spider web algorithm for torque ripple reduction which can be used for both sensored and sensorless BLDC motor. A combination of hybrid filter which is a switched capacitor along with spider web-based controller is employed in the torque ripple reduction circuit. Spider web controller generates switching signals for inverter switches and for controlling the capacitor voltages. For sensored approach, hall effect sensor is used and sensorless operations are done based on detecting zero passage point of counter emf from line voltage difference. The potency of the proposed strategy is validated through the simulation of BLDC motor with spider-based controller for both sensored and sensorless operation.
