　　This paper introduces a three-loop PI control structure based position tracking servo system, SVPWM strategy based on the two-phase hybrid stepping motor driven by H bridge is discussed in detail.In view of the problem of general two-phase SVPWM strategy, an improved one is presented.Zero-voltage vector and a loss reduction switch mode is applied in the new method.Also,the system simulation model was built by using Matlab/simulink, the simulation results validate the good effects of this improved SVPWM control strategy.
