摘要
以大气层内拦截弹气动力和力矩式侧向直接力复合控制系统为研究对象,基于参考模型变结构控制理论设计了拦截弹末制导段复合控制系统,并研究了相应的控制力分配算法、脉冲发动机组调度算法。数学仿真结果表明,该复合控制方法可以很好地实现拦截弹姿态控制。与气动力系统相比,复合控制系统具有更好的动态性能。
Based on model reference variable structure control theory, a new lateral thrust and aerodynamic force blended control method is proposed for endoatmospheric kinetic interceptor in this paper. It also studies the corresponding control command distribution algorithm and impulse motors scheduler algorithm. The simulation results show that this method can realize the attitude control of the interceptor very well, and the blended control system has better dynamic qualities, comparing with the aerodynamic control system.
