The working principle of SVPWM strategy of the system driven by double-H bridge was illustrated and the formulas of the parameters and the basic constrain condition were presented. Also,the system simulation model was built by using Matlab/Simulink, the simulation results demomstrate hight performance of the servo system and validate the effects of the strategy. Key words: position tracking; SVPWM; stepping motor
