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 disturbance. In this paper, the mathematical model of PMSM and the flux weakening control theory are analyzed at first. Then 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 account. In the MATLAB/Simulink environment, a double closed-loop model of flux weakening speed control of PMSM is presented. Finally simulation experiments prove that the control strategy can improve both the speed range of PMSM and the ability to resist load disturbance.
