摘要:

针对于超声速导弹的参数时变、不确定的特点，在超声速导弹简化模型的基础上研究了滑模变结构控制方法，通过理论分析和仿真实践证明了滑模控制系统对于不确定系统具有较好的控制效果。并且与PID控制方法进行了对比，发现了滑模控制方法较PID控制方法具有更强的鲁棒性。证明了滑模法对于不确定超声速导弹的有效性。

Abstract:

Based on the uncertain supersonic missile simplified model parameters that are time-varing and uncertain，this article focuses on the research of sliding-mode control.Through the theoretical analysis and the simulation，it is proved that the sliding mode control for the uncertain system has a better control effect.And compared with the PID control method，sliding mode control has better robustness.The validity of the sliding mode control of uncertain supersonic missile is proved.
