摘要:

针对滑行转弯导弹拦截高机动目标的制导控制系统设计问题,提出了一种基于全驱系统和反步法相结合的制导控制一体化设计方案。首先,考虑目标的机动特性,建立了二阶严格反馈的制导控制一体化非线性模型,消除了中间过程量,简化了建模和计算过程。其次,设计降阶状态观测器,对包含目标未知机动、系统未建模部分、气动参数等扰动进行估计,并在控制器中进行前馈补偿。随后,基于高阶全驱系统方法,结合反步控制方法,设计具有拦截角度约束的制导控制一体化方案,使用极点配置方法,得到闭环系统控制系数矩阵,满足期望的系统性能。引入Lyapunov函数,证明闭环系统稳定性。最后,通过不同场景和对比仿真试验,证明了所设计的制导控制一体化方案的有效性、优越性和鲁棒性。

Abstract:

Aiming at the problem of high frequency oscillation of instantaneous overload of high maneuvering target and uncertain time-varying of line-of-sight angle at the end of guidance, an integrated design scheme of guidance and control based on fully actuated system and backstepping method is proposed in this paper. Firstly, considering the maneuvering characteristics of the target, a second-order strict feedback guidance and control integrated nonlinear model is established, which eliminates the intermediate process quantity, simplifies the modeling and calculation process, and designs a reduced-order state observer to estimate and compensate the system disturbance. Secondly, under the framework of backstepping method, combined with the high-order fully actuated system method, the guidance control law with interception angle constraint is designed. Finally, the pole assignment method is used to obtain the control coefficient matrix of the closed-loop system, and the Lyapunov function is introduced to prove the stability of the system. The effectiveness, superiority and robustness of the designed guidance and control integration scheme are proved by different scenarios and comparative simulation experiments.

Key words: high-order fully actuated system, integrated guidance and control, interception angle constraint, backstepping control, reduced-order extended state observer
