摘要
针对目标作大机动时的导引问题,提出了一种类似Lyapunov法得出的L2增益性能指标的鲁棒导引律(L2RG),并运用遗传算法对其中的参数进行了优化.此导引律设计简单,避免了H∞制导律中求Hamilton-Jacobi偏微分不等式的解析解.通过仿真结果比较,验证了此导引律可以在相同时间内明显地减少追踪者的脱靶量.
To solve the problem of intercepting big maneuvering target, L2 robust guidance (L2RG) law is proposed, which is similar to Lyapunov theory. The parameter of L2RG is optimized using genetic algorithm. Certainly, the guidance law is simple and avoids solving Hamilton-Jacobi partial differential inequation in H∞ guidance law. The simulation results show that the missile can effectively intercept the target in the same time.
