摘要:

针对临近空间动能拦截器, 提出了一种高精度、低能耗的姿轨一体化复合控制方法。首先, 基于拦截器运动学、动力学方程、执行机构特性及全捷联导引头结构, 建立了全捷联姿轨复合控制拦截器制导控制系统模型;其次, 利用反正切函数设计了包含体视线角约束的映射函数, 并针对姿轨耦合问题, 结合高阶滑模控制设计了姿轨一体化复合控制律, 在满足体视线约束和交会角约束的同时,完成了多个控制任务;最后, 基于李雅普诺夫稳定性理论证明了控制律控制下系统的稳定性, 并通过仿真验证了一体化设计方法的优越性、映射函数约束的有效性,以及控制律的鲁棒性。

Abstract:

An attitude and trajectory integrated compound control method with high precision and low energy consumption is proposed for the near space kinetic interceptor. Firstly, based on the kinematics and dynamics of interceptor, characteristics of actuators and the structure of full strapdown seeker, the guidance and control system model of the full strapdown attitude and trajectory compound control interceptor is established. Secondly, the mapping function including the body line-of-sight is designed using the arctangent function. Aiming at the attitude and trajectory coupling problem, combined with the high order sliding mode control, the integrated attitude and trajectory compound control law is designed to achieve multiple tasks while satisfying the body line-of-sight constraint and the impact angle constraint. Finally, the stability of the system controlled by the proposed control law is proved based on Lyapunov stability theory, and the superiority of the integrated design, the effectiveness of the mapping function's constraint and the robustness of the proposed control law are verified by simulation results.

Key words: kinetic interceptor, compound control, attitude and trajectory coupling, sliding mode variable structure control, integrated guidance and control, state constraint
