摘要
大气层外动能拦截器姿态控制系统的执行机构为六台常值推力发动机,为弹体稳定的跟踪目标提供非连续的常值推力,而使用PWPF调制技术可以将常值推力等效为连续推力;动能拦截器姿态控制系统具有强耦合和明显非线性的特点,对经过简化的姿控系统设计出线性二次型最优跟踪控制律,使用经PWPF调制技术等效的连续推力来实现动能拦截器的姿态控制,并进行了仿真。
Actuators of the KKV attitude control system employ 6 constant thrust on-off jets on the stern,which provide the constant discrete power to track the target stably,and the constant thrust can be equivalent to continuous thrust; the KKV attitude control system presents the feature of close coupling and non-linearity. Design the linear quadratic tracking control method to the simplified attitude system and use the continuous thrust, transformed by PWPF modulation,then make out the control and simulation result.
