Abstract:Flux switching permanent magnet (FSPM) machine having high torque density and robust rotor structure is suitable for brushless AC (BLAC) operation, and the classical vector control (VC) and direct torque control (DTC) method can be employed in the FSPM machine systems. The direct torque control system has excellent dynamic performance of electromagnetic torque, however, the dynamic performance of the speed is affected by the PI parameters of the speed closed loop. Hence, this paper investigated a control method to achieve the optimal dynamic performance of the speed. Based on the integration balance of sine value of the torque angle, this method can make the speed and the electromagnetic torque converge simultaneously after the speed adjusting only once. Thus, the best possible dynamic response for the speed can be achieved. The experimental results verify the correctness and effectiveness of the proposed algorithm. © 2017 Chin. Soc. for Elec. Eng.
