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.

在 BLDC 电机中，换相时进相和离相电流偏差的差异会导致转矩脉动，从而导致振动和噪声，从而限制了它们在某些应用中的使用。本文提出了一种基于仿生蜘蛛网算法的简单控制器，用于降低转矩脉动，可用于有传感器和无传感器 BLDC 电机。在转矩脉动降低电路中采用了混合滤波器（开关电容器）和基于蜘蛛网的控制器的组合。蜘蛛网控制器生成用于逆变器开关和控制电容器电压的开关信号。对于有传感器的方法，使用霍尔效应传感器，并基于从线电压差检测反电动势的零通过点来完成无传感器操作。
