为提高步进电机控制系统的动态性能和鲁棒性，将滑模变结构控制应用到两相混合式步进电机的位置控制系统中，通过选择合适的切换函数和趋近率，设计滑模控制器取代传统PID控制的位置环和速度环，使系统控制性能得到较大改善。利用Matlab／Simulink进行仿真，并通过实验进行对比验证，结果显示，滑模变结构控制相比于传统PID控制，具有响应速度快、无超调、抗扰动能力强等优点，由此表明了滑模控制在两相混合式步进电机位置控制系统中的有效性和优越性。

In this paper , sliding mode control was applied to two-phase hybrid stepping motor's position servo system to improve the dynamic performance and robustness .With appropriate switching function and reac-hing law, the sliding mode controller was designed replacing of the position loop and velocity loop of tradi-tional PID control , and the performances of the control system were greatly improved .The system was mod-eled in the Matlab/Simulink software , and the effects were compared through the experiments .The results show that sliding mode control makes quicker response , less overshoot , and stronger anti-disturbance ability , which demonstrates the validity and superiority of sliding mode control in two-phase hybrid stepping motor's position system .
