自适应变结构控制在弹道导弹中段控制的应用

Application of Adaptive Variable Structure Control in the Middle Course of Ballistic Missile

随着弹道导弹技术的发展,中段机动变轨需要进行高精度的姿态指向、快速的大角度机动以及有效地节省能量等复杂的姿态控制。该文将自适应变结构控制应用于弹道导弹中段姿态控制中,推导了滑模到达条件,设计了相应形式的切换函数,给出了一种参数选择方案并设计了一种控制器以抑制抖振,给出了详尽的实现方法。仿真结果表明,该方法可以很好地实现中段姿态控制,具有良好的应用意义。

With the development of ballistic missile, the maneuver in the middle course needs high - precision, fast and less - fuel control. Adaptive variable control is used for middle course control of ballistic missile and the method of realization is provided. This paper deduces the reaching condition of sliding - mode and the corresponding switching functions are designed. A kind of plan for choosing parameters is given and a kind of controller is designed to restrain the oscillation. The simulation result proved that this plan can realize the control in the middle course and is useful to application.
