摘　　要：变结构控制是解决在飞行过程中参数、干扰不断变化的导弹控制的一种新途径。基于Ackermann规则的滑态变结构控制器,在所设计的滑态函数中引入全程滑态因子,既能保留基于Ackermann规则设计变结构控制器简单的优势,又消除了能达阶段,实现姿态控制系统的全局鲁棒性控制,仿真结果表明该控制器性能较为满意。Variable structure control （VSC） is a new way to solve problems like constant change of parameters and interference during the fight of missiles. Put forward one variable structure controller based on Ackermann＇s rule, and adopt global sliding factors in sliding function. It not only preserves the advantage of designing VSC based on Ackermann＇ s rule, but also eliminates the reaching interval. Attitude-control system based on the control way has global robustness. The result shows that the controller performance is good.
