拦截器姿态控制系统切换控制方法研究

Research on switch control method for interceptor attitude control system

为增强拦截器姿态控制系统的鲁棒性,提出了一种切换控制方法来控制拦截器的姿态。该切换控制方法主要包括双重推力水平切换,相平面控制律与准滑模控制律切换和角度反馈切换。给出了高水平推力和低水平推力的切换逻辑,相平面控制与准滑模控制律的切换准则和角度反馈中俯仰角和攻角的切换策略。仿真实验表明,采用切换控制方法所设计的姿控系统可以适应大气层内外飞行,鲁棒性较强。

To enhance the robustness of interceptor attitude control system, a switch control method is presented to control the attitude of interceptor. The switch control method includes the double thrust （DT） switch, the switch between phase plane control（PPC） method and quasi-slide control （QSC） method, and the angle feedback（AF） switch. The switch logic between high thrust and low thrust, switch rule between PPC methed and QSC methed, and the switch maneuver between pitching and attacking in AF are given. The simulation results indicate that the proposed switch control method can fly in either endoatmosphere or exoatmosphere and has a good robustness.
