This article proposes sliding-mode-control-based guidance strategies for a team comprised of aircraft and a defending interceptor against an attacker. The proposed guidance strategies are based on the line-of-sight guidance concept. Problems such as performance degradation under large heading angle errors, arising from linearization of engagement dynamics, are circumvented due to the nonlinear framework considered here. We show that knowledge of the bound on attacker acceleration suffices to ensure interception of an attacking interceptor. Cooperative strategies are derived for the aircraft–defender team, corresponding to cost functions based on the $\ell _p$ norm, using static optimization at each time instant. Simulations validate the efficacy of the proposed strategies.

视线法协同主动飞机保护制导

本文为由飞机和防御攻击者的防御拦截器组成的团队提出了基于滑模控制的制导策略。拟议的指导策略基于视线指导概念。由于这里考虑的非线性框架，可以避免诸如由于接合动力学线性化而导致的大航向角误差下的性能下降之类的问题。我们表明，对攻击者加速的限制的知识足以确保拦截攻击拦截器。为飞机防御者团队制定了合作策略，对应于基于$ \ ell _p $规范，每次都使用静态优化。仿真验证了所提出策略的有效性。
