doi:10.11985/2019.01.001

Abstract

Abstract:

As internal permanent magnet synchronous motor(IPMSM) running at weak magnet field with disturbance of a fluctuated current of axis, an intelligent control strategy is put forward based on fuzzy theory. By the means of simulation model built by Matlab/Simulink software, and the functions on restraining dq axis current fluctuation by the control strategy during the operation on weak magnet with sudden load of permanent magnet synchronous motor is investigated. The simulation results show that control strategy can reduce the fluctuation of currents during weak magnet operation with an accident added load.

Key words: Internal permanent magnet synchronous motor, field weaking control, fuzzy PI control
