PI^λD^μ Approach for High-Efficiency BLDC Motor Control

In this study, we present the design and implementation of a Fractional-Order Proportional-Integral-Derivative (FOPID), also known as PI^λD^μ speed controller for Brushless DC (BLDC) motors. BLDC motors are widely used in various applications due to their high efficiency and performance. However, effective control of BLDC motors remains a challenging task due to nonlinear properties and variable operating conditions. Results show that FOPID demonstrates significantly outperform; their integer-order counterpart on performance criteria such as overshooting, rise time, transient duration, and undershoot, due to the inherent flexibility of the volume distribution.
