摘要: 为应对来自临近空间高超声速飞行器的威胁,对作战空域在35 km以上高空的反临近空间拦截弹的需求越来越迫切。姿态控制系统的执行机构为6台常值推力发动机,为弹体稳定的跟踪目标提供可多次开启的常值推力,而使用PWPF调制技术可以将常值推力等效为连续推力;拦截器姿态控制系统需要克服轨控开启时带来的较大干扰,因此基于自抗扰方法设计了控制器,控制信号经PWPF调制后得到脉冲开关信号实现拦截器的姿态控制。仿真结果表明,自抗扰控制器具有更好的快速性与稳定性,且更方便与PWPF调制器串联使用。

Abstract: There is a growing need for interception missile that can work above 35 km in order to cope with the threat from near-space hypersonic vehicles. The attitude control system employs six constant thrust on-off jets and only identifies the pulse on-off signals to track the target steadily. The pulse-width pulse-frequency (PWPF) is applied to make the continuous variable be equivalent to on-off variable. To overcome the interference, the attitude control system is designed using active disturbance rejection control (ADRC). The PWPF makes the continuous control signal be on-off signal and achieve controlling attitude of the missile. The simulation result shows that the output signal of the ADRC controller is more adaptive to be used with PWPF, and the ADRC controller has better rapidity and stability.

Key words: lateral thrust, intercept near-space vehicles, attitude control, pulse-width pulse-frequency(PWPF), active disturbance rejection control(ADRC), simulation
