摘要
针对自主式水下机器人稳定性控制问题进行了研究.首先对水下机器人的总体结构及其在水中的运动特性进行了分析,建立水下机器人系统的动力学模型;然后建立了直线、方向和位置的运动稳定性分析方法,确定了纵向稳定性和侧向稳定性准则,提出了基于特征值的稳定性要求;最后设计了无源自适应控制器,针对水下机器人在水中悬停和运动时易受海流影响的问题,建立了自适应补偿方法,进而确定了输入的不确定性补偿方法.对自主式水下机器人进行多方向的运动稳定性控制试验,通过试验修正稳定性控制参数,验证了设计的水下机器人运动稳定控制器的有效性和可靠性.
The problem focusing on stability control of autonomous underwater vehicle （AUV） was studies .First of all ,the overall structure of the underwater vehicle and the motion characteristics in water were analyzed and the dynamics model of the AUV system was established .Secondly ,put for-ward the analytical methods for the line ,direction and position stability ,in which the longitudinal and lateral stability criterions of stability were formulated ,and the requirements for stability were raised based on characteristic value .The passive adaptive controller was designed .In connection with the problem that the underwater vehicle is easily affected by the ocean current when hovering or moving in the water ,the adaptive compensation method was established and then the method for compensating the uncertainties was determined .Finally ,the experiments of multi-directional motion stability was carried out .By adjusting the relative controller parameters ,the validation and reliability of the de-signed stability controller of the underwater vehicle was verified .
