摘要:

设计了一种基于滑模变结构的高速动能弹制导控制算法,并结合高速动能弹自身的弹体特性及作战目标需求,对算法中相关参数进行了设计整定。针对滑模变结构固有抖振问题,设计相应算法抑制抖振,通过建模仿真证实了算法的正确性和可行性。根据仿真结果分析,滑模变结构制导控制算法能够使高速动能弹命中目标,且经处理后的滑模抖振问题也能得到相应的抑制。

Abstract:

A guidance and control arithmetic of hyper velocity kinetic energy missile is designed based on sliding-mode variable structure control. The relevant parameters in the algorithm are designed and adjusted by combining the characteristics of the hyper-velocity kinetic energy missile and the operational mission requirements. The algorithm is used to suppress the chattering problem inherent in the control of sliding mode variable structure, and the modeling simulation confirms the correctness and feasibility of the algorithm. According to the analysis of the simulation results, the hyper-velocity kinetic energy missile can hit its target because of the guidance and control arithmetic, and the processed chattering of sliding mode control can be suppressed.

Key words: hyper velocity kinetic energy missile, parameters tuning, sliding-mode variable structure control, guidance and control, chattering of sliding mode, simulation analysis
