摘要: 为了解决水下目标信息参数测量数据率低带来的制导困难问题, 设计了基于变结构控制的反鱼雷鱼雷(ATT)导引律, 导引律中取变结构控制器使得ATT与来袭鱼雷间视线角保持恒定, 且控制器对模型参数摄动具有强鲁棒性。理论分析表明, 模型参数摄动不影响导引律的稳定性, ATT和目标间视线角能够保持恒定。仿真结果验证了该导引律对模型参数摄动具有强鲁棒性, ATT能够精确命中目标。

Abstract: For solving the difficulty in the guidance of anti-torpedo torpedo(ATT) due to low data ratio of underwater target information detection, an ATT guidance law based on variable structure control is designed, in which a variable structure controller is employed to keep a constant line-of-sight angle between ATT and incoming torpedo, and the con-troller shows good robustness for perturbation of model parameters. Theoretical analysis shows that perturbation of model parameters has no effect on the stability of the guidance law, and the line-of-sight angle between ATT and target can keep constant. Simulation validates that the proposed guidance law has good robustness for perturbation of model parameters, and the ATT with the guidance can hit target precisely.
