摘要：

To improve the dynamic performance of high-speed PMSM control system, an integrated controller for both velocity and current loops is designed based on the nonlinear dynamic math model of PMSM, which, combined with the sliding-mode variable-structure control, applies the precision linearization theory to solve the nonlinear problem of speed-current coupling caused by the close electromagnetic and mechanic time constants of high-speed PMSM. An adaptive method of online parameter identification is designed for the sensorless operation of high-speed PMSM, which, with one math model, identifies the velocity and other motor parameters at the same time. Simulative and experimental results show that the control system has better static/dynamic performance and robustness.
