Objective of the Session:

The Department of Electrical Engineering organized an expert lecture on “Advanced Control Strategies for Special Electric Machines” on 3rd February 2024 for the 6th semester students. The session was delivered by Prof. A. D. Joshi, Assistant Professor at GEC Dahod, who has significant expertise in electric drives, power electronics, and advanced motor control systems.

Prof. Joshi began the lecture with an overview of special electrical machines, including Switched Reluctance Motors (SRM), Permanent Magnet Synchronous Motors (PMSM), Brushless DC Motors (BLDC), and Linear Induction Motors (LIMs). He explained how these machines differ from conventional induction motors in terms of construction, performance, and applications. The expert emphasized the role of modern control techniques in enhancing the performance of these machines.

Outcome

• Vector Control and Field-Oriented Control (FOC) for PMSM and BLDC motors
• Direct Torque Control (DTC) for high-performance drives
• Sensorless control techniques for cost-effective and reliable operation
• Adaptive and predictive control methods for uncertain and dynamic environments
• Applications of AI/ML-based controllers in intelligent drive systems

Prof. Joshi highlighted practical applications of special electric machines in electric vehicles, robotics, aerospace, renewable energy systems, and industrial automation. He also shared insights from industry trends, focusing on how SiC and GaN power devices are enabling compact, efficient, and high-speed drives.

The session concluded with an interactive Q&A session, where students actively asked questions about real-time control implementation, simulation tools, and potential project areas. Prof. Joshi encouraged students to explore MATLAB/Simulink and dSPACE platforms for advanced motor control projects.
