摘　　要：为对磁性敏感的实验装置提供一个无磁干扰、具有一定深度以及姿态稳定的水下测试环境,设计一款基于经典比例积分微分(PID)算法控制的弱磁型四旋翼水下自主航行器。本文通过外形设计,对该自主航行器进行三维建模,从而建立该AUV的运动学模型,进行稳定性分析。通过电气系统以及控制系统的设计与组装,调整各控制参数,成功搭建该自主航行器并进行水池实验。通过实验可知,基于PID控制的弱磁型四旋翼水下自主航行器通过无浮力缆与上位机连接,可以实现定深以及定姿态的功能。同时将各个误差值控制在理想范围内,验证了该控制系统的稳定性以及鲁棒性。In order to provide an underwater test environment with no magnetic interference,a certain depth and a stable attitude for the experimental device sensitive to magnetism,a weak magnetic four-rotor underwater autonomous vehicle based on the classic proportional integral derivative(PID)algorithm control is designed.In this paper,through the shape design,three-dimensional modeling of the autonomous vehicle,the kinematic model of the AUV is established and conduct its stability analysis.Through the design and assembly of the electrical system and the control system,the control parameters are adjusted to successfully build the physical object of the autonomous vehicle and the pool experiment.Through the experiment,it can be seen that the weak magnetic field-based four-rotor underwater autonomous vehicle based on PID control is connected to the upper computer through a buoyancy cable,which can realize the functions of depth and attitude determination.The error value is controlled within the ideal range,which verifies the stability and robustness of the control system.
