采用一类积分型滑模的导弹控制系统设计

The Design of Missile System with Integral Sliding Mode Control

针对不确定导弹过载控制系统,考虑攻角难于测量的特性,引入一类简单积分型滑模面,设计变结构控制律。由于采用简单滑模面,使得设计十分简洁,有效避免了反演设计的微分爆炸。同时通过构造Lyapunov函数分析其稳定性,进行仿真研究举例,仿真结果表明了该方法的有效性。

Due to the unmeasurable characteristics of the attack angle of missile,a variable structure control（VSC） law based on a kind of simple integral sliding mode control method is designed for the uncertain missile system.There are two advantages by applying the simple VSC method.Firstly,the differential bomb problem can be avoided by applying VSC method.Secondly,the control law is simple,which is very easy to be applied in engineering.And the stability of the system is proved by constructing a Lyapunov function.The simulation is done for reference in cases and shows the effectiveness of the proposed method.
