High performance speed control of interior permanent magnet synchronous motors with maximum power factor operation

In this paper, a high performance control applied to speed control of interior permanent magnet synchronous motors. The design strategy is performed with constraint on the power factor, i.e., the power factor is maximized. In order to enhance the performance of the control system, a decoupling current vector control strategy is developed to ensure high performance operation. Simulation results reveal the effectiveness of the proposed controller.
