Electronic assisted brake systems require permanent magnet synchronous motor(PMSM) to work in a larger speed range,and to maintain a certain ability to resist load *** this paper,the mathematical model of PMSM and the flux weakening control theory are analyzed at *** a control strategy is proposed based on maximum torque per ampere(MTPA) control combined with flux weakening control principle,which also takes the current compensation decoupling into *** the MATLAB/Simulink environment,a double closed-loop model of flux weakening speed control of PMSM is *** simulation experiments prove that the control strategy can improve both the speed range of PMSM and the ability to resist load disturbance.

In order to control electric vehicle PMSM（Permanent Magnet Synchronous Motor） stably run in whole speed range,this paper designs a control algorithm combining linear interpolation look-up method MTPA（the Maximum Torque per Ampere） control and modulation hysteresis loop flux weakening *** the purpose of stable control is achieved when the motor speed and the torque changed at any time during the *** algorithm uses flux weakening algorithm to compensate the instruction current of MTPA control,then correct the current vector trajectory and speed up the ***,the bench test and driving experiment on the electric vehicle shows that the algorithm can run steadily and achieve the desired goal.
