基于T-S模糊观测器补偿的UUV控制方法
摘要：
基于T‑S模糊观测器补偿的UUV控制方法，涉及一种UUV控制方法。为了解决在有海流干扰时UUV跟踪航迹不精确的问题。包括：获取UUV下一步的期望航迹；姿态控制器根据期望轨迹进行跟踪误差，解算出下一步垂直舵与水平舵的舵角信息；T‑S模糊观测器根据海流干扰、当前UUV状态信息和航迹位置误差对UUV进行观测，估计出UUV下一步的状态信息；将UUV下一步的状态信息作为航速控制器的输入信号，获得推进器的下一步的推力；根据垂直舵与水平舵的舵角信息和推力，对UUV进行控制，获得UUV的运动状态，进而确定UUV的航迹，判断该航迹是否达到期望轨迹。本发明用于UUV跟踪水下线缆或管道、水下搜救、深海资源探测及地形探测。
摘要（英）：

The invention relates to a UUV control method and discloses a UUV control method based on T-S fuzzy observer compensation to solve the problem that the UUV track is inaccurate under ocean current interference.The method comprises the steps that the expected track of a UUV in the next step is acquired; an attitude controller conducts error tracking according to the expected track and works out the rudder angle information of vertical rudder and diving rudder in the next step; a T-S fuzzy observer observes the UUV according to ocean current interference, the current state information of the UUV and track position error, and estimates the state information of the UUV in the next step; the thrust of a thruster in the next step is acquired with the state information of the UUV in the next step as an input signal of a speed controller; the UUV is controlled according to the rudder angle information of vertical rudder and diving rudder and the thrust, the motion state of the UUV is acquired, and then the track of the UUV is determined and whether the track coincides with the expected track is judged.The method is used for UUV tracking of underwater cables or pipelines, underwater search and rescue, deep-sea resource detection and terrain detection.
