The Research on Control Method of Variable Speed System of Permanent Magnet Synchronous Motor

Abstract

In order to solve the problem that the traditional PI controller can not meet the high performance speed control requirement of permanent magnet synchronous motor, the fuzzy control theory is applied to the speed loop of speed control system of permanent magnet synchronous motor, and realized the parameters tuning in real time of PI controller. Finally, by means of the simulation experiment, the solution verified the new fuzzy PI control system has good robustness to the system load and disturbance.
