防空导弹直接力／气动力复合控制系统设计

直接力和气动力复合控制技术是先进防空导弹对付高速机动目标、兼有反导能力以 及发 展成为动能拦截弹最现实有效的技术途径。针对力矩式复合控制方法，为减小由于弹体滚动 所引起的耦合影响，建立了俯仰－偏航通道短周期运动模型；在弹体慢旋条件下给出了参考 信号状态空间模型，利用线性二次型最优跟踪控制方法设计了复合控制姿态稳定系统，并基 于分离原理设计了参考信号状态观测器。仿真结果表明系统对制导指令的响应时间小于0.1 秒，对螺旋机动弹道目标的拦截脱靶量为0.34米，说明该复合控制方法具备直接碰撞目标的 能力。〖JP〗

Compound Control System Design with Direct Thrust and Aerodynamic Force for Air Defence Missile

The compound control technology with direct thrust and aerodynamic force for advanced air defence missile is the most effective way to intercept high-speed maneuvering targets,possess the ability of missile-defense and even develop into kinetic energy interceptor.The short-period motion model of pitch-yaw channel was established in order to reduce the coupling effect caused by the roll of missile body.A state space model of reference signal was presented under the condition of slow spin and the compound control attitude stabilization system was designed by using linear quadratic optimal tracking control theory.Based on the separation theory,the state observer of reference signal was also studied.Simulation results show that the response time for the guidance command is less than 0.1 second and the miss distance to the helical maneuvering ballistic target is 0.34 meter.It is concluded that the compound control system can meet the need of hit-to-kill.
