Abstract: The stability of a Brushless Direct Current (BLDC) motor is crucial for the effective operation of a drive system, as it is influenced by initial operating conditions that exhibit chaotic behavior. This paper addresses the stabilization of chaotic BLDC motor dynamics using the concept of finite-time stability. To achieve this, three simple yet effective controllers have been designed to suppress the motor's chaotic behavior. Additionally, the proposed controllers are evaluated and compared based on their performance indexes i.e. settling time and peak overshoot. The performance of the controllers is analyzed in a MATLAB simulation environment, and the results are further validated through real-time testing using an STM32 board as a cost-effective Hardware-in-the-Loop (HIL) emulator. The comparison demonstrates a consistent trend and close agreement between the MATLAB simulations and real-time results, thereby confirming the effectiveness of the proposed controllers.
