摘要:

针对高超声速飞行器俯冲段拦截区规避与终端落角约束问题,提出一种基于滑模控制的跟踪制导方法。通过参数化设计纵向俯冲弹道与横向机动弹道,将复杂的过程约束转化为路径点约束,并利用序列二次规划求解落速最优弹道参数,生成满足终端落角约束与拦截区规避的参考轨迹;基于飞行器非线性运动模型,设计滑模跟踪制导律,对参考轨迹进行跟踪。仿真结果表明:扰动条件下,该制导方法产生的控制量连续平滑,具有较高的终端落角与落点控制精度,其中落角偏差不超过0.5 °,脱靶量控制在1.3 m以内。所提方法不依赖导引头对目标的探测信息,能够一定程度降低制导系统的复杂程度。

Abstract:

A sliding mode control-based tracking guidance method is developed to address the challenges of interception zone evasion and terminal fall angle constraints during the hypersonic vehicle’s dive phase. Through parametric design of longitudinal dive trajectory and lateral maneuver trajectory, complex process constraints are transformed into way-point constraints. The sequential quadratic programming method is employed to solve optimal trajectory parameters with maximum terminal velocity, generating reference trajectories that satisfy both terminal impact angle requirements and interception zone avoidance. Based on the nonlinear motion model of the aircraft, a sliding mode tracking guidance law is designed to track the reference trajectory. Simulation results show that the control quantity generated by the guidance method is continuous and smooth under the disturbance condition, achieving high precision in both terminal impact angle and position control, where the impact angle deviation is less than 0.5°, and the miss distance is controlled within 1.3 m. The proposed method eliminates reliance on target detection information from seekers, thereby reducing the complexity of the guidance system to some extent.

Key words: hypersonic vehicle, interception zone constraint, impact angle constraint, dive-phase, sliding mode control
