Abstract

It is necessary to conduct current decoupling control, because there is non-linear coupling in PMSM servo system with position, speed and current closed-loops. Based on voltage space vector control and current vector control program, it is enable to make the linear decoupling come true in PMSM servo system. Though analyzing the math model of the servo system, facing to i_d = 0 strategy of vector control, the simulation models are separately constructed under Matlab/simulink.. From the results of the simulation, the model of servo system based on SVPWM has a approved performance for the speed and position control, the steady-state value of speed has no static margin, and the steady-state value of position has no overshoot.
