摘要

Managing heat dissipation, minimizing torque ripples, and attaining precise speed and position control against sensorless operating at low speeds are the main enhancements for Brushless Direct Current (BLDC) motor drives. This work addresses these challenges through a hybrid technique of power factor correction in an integrated buck–boost–buck (ib3) converter-fed sensorless BSLDC motor using a novel regulating method. A flux linkage-based sensorless control method is used targeting a three-phase BLDC motor. The approach incorporates a Fractional-Order Proportional–Integral–Derivative (FOPID) controller and hybrid optimization techniques, namely Aquila Optimizer and Tasmanian Devil Optimization (TDO), to form the Optimized FOPID (OFOPID) approach. The ib3 converter serves as a front-end converter with low ripple voltages to the three-phase inverters. This is designed using a single switch and no DC-side filter components. The OFOPID controller reduces steady-state errors and system disturbances through auto-tuned gain optimization. MATLAB simulations and comparative analyses prove that the recommended algorithm is useful for lowering the torque ripple of BLDC motors and minimizing vibrations in practical applications while improving the efficiency of energy use and optimizing the parameters.
