基于变结构控制的反鱼雷鱼雷姿态解耦控制

反鱼雷鱼雷由于攻击对象的特性要求具备较好的机动性,鱼雷作姿态机动时控制通道间的耦合,使得传统鱼雷控制技术无法达到控制目的,本文在构建反鱼雷鱼雷姿态运动子系统状态方程的基础上,采用变结构控制策略设计了反鱼雷鱼雷姿态控制器,理论推导和仿真表明:所设计的控制器能够使得反鱼雷鱼雷姿态角稳定地跟踪弹道所需航向角,实现了鱼雷姿态子系统间的解耦控制.

Decoupling-control system based on variable-structure control for anti-torpedo torpedo poses

The anti-torpedo torpedo should have flexible performances to cope with the motion characteristics of the objective torpedo under attack. Conventional control technology cannot achieve this goal because of the coupling between controlled channels of the anti-torpedo torpedo when the objective torpedo is in pose maneuver. We design the pose controller for the anti-torpedo torpedo by adopting variable structure control strategy in constructing the state-space equation for the pose motion subsystems of the anti-torpedo torpedo. Theoretical analysis and simulation show that the controller makes the pose angle of the ant-torpedo torpedo steadily track the required heading angle, and achieve decoupling between controlled channels of the anti-torpedo torpedo when the objective torpedo is in pose maneuver.
