摘要:

针对高机动飞行器拦截过程中的动态滞后及多约束问题,构建三维拦截制导二阶系统模型,提出一种终端角约束制导律。针对目标机动引起的干扰,提出一种有限时间收敛三阶扰动观测器,将系统模型视为“观测器-控制器”系统,基于超螺旋滑模控制理论提出一种非奇异有限时间收敛控制器。此外,考虑驾驶仪的动态响应,将系统模型扩展至四阶,基于反步法和动态面控制理论,将视线(line-of-sight,LOS)角误差和LOS角速率控制在零附近的邻域内,实现对目标的精确拦截。最后,通过不同场景的仿真验证了所提制导律的良好性能。

Abstract:

Addressing the dynamic lag and multi-constraint problems in the interception of high-maneuverability aircraft, a second-order system model for three-dimensional interception guidance is constructed, and a terminal angle constraint guidance law is proposed. A finite time convergent third-order disturbance observer is proposed to address disturbances caused by target maneuvering. The system model is treated as an “observer-controller” system, and a non-singular finite time convergent controller is proposed based on the theory of super-twisting sliding mode control. In addition, considering the dynamic response of the autopilot, the system model is extended to fourth order. Based on backstepping and dynamic surface control theory, the line-of-sight (LOS) angle errors and LOS angular rates are controlled within the neighborhood of zero, achieving precise interception of the target. Finally, the good performance of the proposed guidance law is verified through simulations in different scenarios.

Key words: super-twisting sliding mode control, terminal angle constraint, autopilot lag, disturbance observer, back-stepping design
