针对战术寻的导弹在追踪平面内的非线性运动学问题 ,提出了一种鲁棒制导律。与传统的制导方法不同 ,这种制导律不需对目标运动进行任何假设 ,也不必对目标加速度进行实时估计 ,因此 ,在对目标机动信息一无所知的情况下 ,制导律本身具有很强的鲁棒性。通过分析推导 ,给出了解析形式的 H∞ 制导律。数字仿真结果表明 ,H∞ 制导律具有良好的跟踪性能和鲁棒性。 Aiming at the nonlinear kinematics of tactical missiles in the tracking plane, a robust guidance law is proposed. Unlike traditional guidance methods, the guidance law does not need to make any assumptions about the target motion and does not need to estimate the target acceleration in real time. Therefore, the guidance law itself is very strong without knowing anything about the target maneuvering information Robustness. By analyzing and deducing, an analytical form of H∞ guidance law is given. The numerical simulation results show that the H∞ guidance law has good tracking performance and robustness.
