反舰导弹的自适应全局滑模变结构控制

为了消除变结构控制的到达阶段，保证系统在整个控制过程中的鲁棒性，提出了一种自适应全局滑模变结构控制方法。该方法利用自适应控制来调节变结构控制器的参数，对系统不确定项的上界进行估计，保证了整个闭环控制系统的渐近稳定性。考虑到反舰导弹的法向过载输出存在非最小相位特性，采用了输出重定义技术来解决。在此基础上，应用自适应全局滑模变结构控制方法设计导弹的飞行控制系统，保证了导弹的新输出量渐近地跟踪其期望值。仿真结果证明了所提出的控制方法的有效性。

Adaptive Global Sliding Mode Variable Structure Control for Anti-ship Missile

In order to remove the reaching phase from variable structure control, and to guarantee the system robustness during the whole control process,an adaptive global sliding mode variable structure control approach is proposed.Using adaptive control,this approach adjusts a parameter of the variable structure controller to estimate the upper bound of system uncertainties,which ensures the asymptotic stability of the whole close-loop control system.For the normal overload output of anti-ship missile is of nonminimum phase,the output-redefinition technique is adopted to solve it.On the basis of it,the anti-ship missile flight control system is designed using the adaptive global sliding mode variable structure control approach.The new output of the missile is guaranteed to asymptotically track the desired value.Simulation results show the effectiveness of the proposed control method.
