Design Analysis of SSD Optimized Speed Controller for BLDC Motor

Abstract

Brushless Direct Current (BLDC) motor is widely applied for both domestic and industrial applications especially in computer peripheral devices and electric vehicles. This paper introduces BLDC motor design using Social Ski Driver (SSD) optimized speed controller. Better efficiency, high power density, good reliability, less noise & maintenance, and the use of simpler control mechanisms are major benefits of the BLDC motor. Proposed work mainly focuses on torque ripple compensation with speed control at low cost. The use of a small DC link capacitor instead of a bulkier capacitor helps to reduce ripples by using Social-Ski Driver optimized controllers. However, torque reduction with reasonable speed control has not been achieved in existing works. So, the proposed work planned to design an advanced controller with the recent bio-inspired algorithm to control the PWM signal. The proposed work will be implemented in MATLAB Simulink working environment for research analysis. From the implementation result, the proposed work achieves 422 (rad/sec) speed, 0.03(Nm/A) torque constant, and 25 (MW) rated power.
