| Abstract: | In order to reduce the failure rate of high voltage circuit breakers,a permanent magnet synchronous motor(PMSM)driven high voltage circuit breaker operating mechanism and its control method were studied.Permanent magnet synchronous motor vector control system can achieve high precision,high dynamic response,a wide range of speed and position control.In this paper,the mathematical model of permanent magnet synchronous motor was described.On the basis of mathematical model,three kinds of current control strategies of permanent magnet synchronous motor vector control were analyzed:i d=0 control,MTPA maximum torque current ratio control and field weakening control.The control principle and characteristics of the three control strategies were described,and the three control strategies were verified by simulation. |
