基于积分滑模的导弹过载控制稳定性研究

针对导弹过载控制系统,考虑了导弹舵机的一阶动态特性,引入一类积分型滑模面,设计变结构控制律,对导弹的过载和角加速度进行控制。然后构造Lyapunov函数证明其稳定性,仿真算例表明了该方法有较好的鲁棒性和快速性。在此基础上,考虑工程应用的需要,提出了一种形式简单的控制规律,减少了控制信号的计算量,仿真结果表明,该控制律具有优良的控制效果。

Research on the Stability in the Overload Control of Missile Based on a Kind of Integral-Type Sliding Surface

Considered the first-order transient characteristic of the autuator of a missile and introduced a kind of integral-type sliding surface,a variable structure control(VSC) law was designed to control the overload and the angel acceleration of a missile.And the stability of the system was proved by constructing a Lyapunov function.Some simulation was done to give examples,which shows better robustness and speediness compared with other method.On this basis,considered the demand of engineering application,a simple control law was proposed to make the calculation of control signal easy.Finally,the simulation results are presented to show the excellent control effect of the proposed method.
