PM Synchronous Motor Drive for Electric Vehicles by Using an Adaptive Controller

摘要

In this paper, the adaptive control method is applied to a Permanent magnet synchronous motor (PMSM). An Adaptive control which depends on the input-output feedback linearization for torque and speed control of the PMSM is developed. Through the feedback linearization, direct and quadratic current decoupling and controls are achieved. The torque becomes only proportional to the quadratic current and direct current is controlled to zero. The adaptive control is used to estimate the uncertain plant parameter variation and also it does not need any prior information of real parameter. With the help of simulation result, the adaptive control scheme is performed. From these result, it is clear that the proposed method obtains high dynamic performance like vector control.
