A robust MTPA controller for high efficiency IPM synchronous motor

Abstract

In electric vehicles (EV), an interior permanent magnet (IPM) synchronous motor (IPMSM) is popularly used as traction motors. In order to make good dynamic characteristic and control characteristic, such as small overshoot, maximum torque output, optimum efficiency operation, good transient response and the ability of restraining gust disturbance law, this paper presents a new approach. This approach combines maximum torque per ampere (MTPA) control strategy with auto disturbance rejection control (ADRC) to ensure the desired performance in electric vehicle applications. The effectiveness of the proposed control approach is successfully tested by means of simulations. The results show that the controller has good characteristics.
