Synergetic and Sliding Mode Controls of a PMSM: A Comparative Study

What is it about?

Permanent magnet Synchronous machines (PMSM) provide high efficiency, compact size, robustness, lightweight, and low noise; these features qualify them as the best suitable machine for medical applications. Without forgetting its simple structure, high thrust, ease of maintenance, and controller feedback, make it possible to take the place of steam catapults in the future. This paper presents the synergetic control approach for PMSM. Synergetic control theory is purely analytical and is based on nonlinear models, provide asymptotic stability. This approach allows to reduce the chattering phenomenon. To verify the performance characteristics of this approach, we compare it with sliding mode. Simulation results are presented to show the effectiveness of the proposed control method.

Why is it important?

In a modern industrialized country about 65% of electrical energy is consumed by electrical drives. Constant-speed, variable-speed or servo-motor drives are used almost everywhere: in industry, trade and service, house-holds, electric traction, road vehicles, ships, aircrafts, military equipment, medical equipment and agriculture [1]. Permanent magnet (PM) machines provide high efficiency, compact size, robustness, lightweight, and low noise, [2], these features qualify them as the best suitable machine for medical applications [3]. Without forgetting its simple structure, high thrust, ease of maintenance, and controller feedback, make it possible to take the place of steam catapults in the future [4]. The PM motor in an HEV power train is operated either as a motor during normal driving or as a generator during regenerative braking and power splitting as required by the vehicle operations and control strategies.
