摘要

摘要: 鱼雷追踪导引性能的优劣主要取决于导引律的设计。采用球坐标系, 建立鱼雷和目标的3D相对运动方程, 应用变结构控制理论, 设计一种新的鱼雷非线性变结构导引律, 并对其收敛性进行验证, 在目标进行正弦机动的条件下进行计算机仿真, 并与H∞导引律导引性能进行比较。结果表明, 在变结构导引律下, 鱼雷能在较短时间内追踪到目标, 并且目标线方位角和高低角始终保持在初始值附近, 抖振较小, 法向过载也得到很好的控制, 不随鱼雷与目标距离的减小而增大, 故该导引律可有效提高鱼雷的追踪导引性能, 并具有良好的鲁棒性。

Abstract: Torpedo′s target pursuit capability highly dependents on the design of high performance guidance law. In this paper, equations for 3D relative motion between torpedo and targets are built by using global coordinates. Variable structure theory is used to design a new torpedo nonlinear guidance law, and the convergence of the variable structure guidance law is validated. Simulation is conducted for target sine maneuver, and the result is compared with that of the H∞ guidance law. The comparison shows that the variable structure guidance law can help torpedo pursue target within shorter time, and the azimuth angle and pitching angle always keep around the initial values. Furthermore, the normal load doesn’t increase with the decrease of the distance between torpedo and target. So, the present guidance law is ef-fective for torpedo pursuit with good robustness.
