Abstract :
The flux-weakening control is needed for the permanent magnet synchronous motor in the pure electric vehicle when it is working in the high speed process, in which the parameters of PMSM is changed such as direct-axis inductance, quadrature-axis inductance and permanent magnet linkage, and the control accuracy of PMSM and the vehicle performance will both be affected. A stator current compensation method based on fuzzy control theory is proposed, and the models of motor control and complete vehicle are established in the Matlab/Simulink environment. The simulating result showed that the flux-weakening control strategy based on stator current compensation is valid and feasible.
