Dynamic control of permanent magnet synchronous motors for automotive drive applications

By Paul Stewart and V. Kadirkamanathan

Abstract

Due to factors such as high power density and efficiency, low torque ripple and maintenance, and extremely wide operating speed range, permanent magnet AC motors (PMAC) are the subject of intense development for traction drive applications. Maximum torque production for both traction performance and electronic gearchanging requires the operating condition to be as close to voltage saturation as possible in the flux weakening region. A fully dynamic model reference flux-weakening controller with feedback linearisation decoupling is presented, which allows the maximum torque-speed trajectory to be followed dynamically, without saturation of the current controller
