针对升力式高超声速飞行器再入滑翔侧向制导问题,提出了一种考虑禁飞区规避的预测校正制导方法.纵向制导采用落点误差预测与指令校正相结合的方式,不断更新倾侧角的幅值,实时修正轨迹纵程.侧向制导设计了一种倾侧角反转逻辑的切换机制,利用航向角误差走廊和航向角导向区域控制飞行器的侧向运动.CAV-H再入滑翔飞行器制导仿真实例表明,该方法不依赖于标准再入轨迹,能够导引飞行器规避禁飞区约束.Monte Carlo仿真验证表明,在随机初始扰动和误差存在的情况下,该制导方法具有良好的鲁棒性.
Aiming at the problem of backward guidance and gliding of LHSV, a prediction and guidance method is proposed, which takes into account the avoidance of avoidance zones. Longitudinal guidance adopts the combination of placement error prediction and command correction to continuously update the amplitude of roll angle Value and real-time trajectory correction. Lateral guidance design a kind of switching mechanism of tilt angle reversal logic to control the lateral movement of the aircraft by using the heading error corridor and the heading angle guidance area.CAV-H reentry gliding aircraft guidance simulation The example shows that the proposed method can guide the aircraft to avoid the no-fly zone constraints, independent of the standard reentry trajectory.Monte Carlo simulation shows that the proposed method has good robustness under stochastic initial perturbations and errors.
