Feedback stabilization for velocity regulation of permanent magnet synchronous motors

This paper investigates feedback stabilization for velocity regulation of the surface-mounted permanent magnet synchronous motors. The motors have been widely used in automatic systems in modern industry. A feedback linearization method is presented to design a stabilizing controller for velocity regulation of the motors. With an unknown load torque disturbance, the closed-loop system is asymptotically stable and the velocity achieves the constant desired value.
