<p>Permanent Magnet Synchronous Motors (PMSMs) are widely adopted in high-performance industrial<br>drives, electric vehicles, robotics, and renewable energy systems due to their high efficiency, compact<br>size, and superior torque density. However, achieving precise and robust speed control of PMSMs<br>remains a challenging task because of nonlinear dynamics, parameter variations, load disturbances, and<br>uncertainties in operating conditions. Conventional proportional–integral (PI) controllers, although simple<br>and widely used, exhibit limited performance under such nonlinear and time-varying conditions. In recent<br>years, Artificial Intelligence (AI)–based control techniques have emerged as powerful alternatives capable<br>of learning system behavior, adapting to uncertainties, and improving dynamic performance. This paper<br>presents a comprehensive study on speed control of a PMSM using an AI controller, with emphasis on<br>intelligent techniques such as Artificial Neural Networks (ANN), Fuzzy Logic Control (FLC), and hybrid<br>neuro-fuzzy approaches. The mathematical modeling of PMSM in the d–q reference frame is discussed,<br>followed by the design methodology of the AI-based speed controller integrated with field-oriented<br>control. Performance evaluation is carried out in terms of rise time, settling time, steady-state error,<br>torque ripple, and robustness against load disturbances. Comparative analysis with conventional PI<br>control demonstrates the superiority of AI controllers in achieving faster dynamic response, reduced<br>overshoot, and improved stability. The results highlight the suitability of AI-based speed control<br>strategies for next-generation high-performance PMSM drive applications.</p>
