Abstract:

The single vector quaternion feedback control algorithm for the Special Topic: Autonomous Underwater Vehicle (AUV) was proposed, which used vectors to represent control input and attitude errors.This algorithm solved the attitude dead zone and multi-turn rotation problem in Euler angle attitude.The above algorithm could realize the attitude and position control in a fully-actuated dish-shaped AUV.In order to demonstrate the efficacy of the algorithm mentioned, the physical model of the dish-shaped AUV was built in the simulation and a digital controller was designed based on quaternion feedback.The experimental results showed that the quaternion feedback control algorithm could make the dish-shaped AUV system move from one arbitrary state to another arbitrary state in the state space.The algorithm regarded the body attitude or position as a single closed loop, thus having larger convergence domain and requiring fewer parameters to tuning than the scheme using Euler angles, which made the debugging of dish-shaped AUV control parameters easier and more convenient in engineering application.

Key words: quaternion feedback, fully-actuated system, dish-shaped AUV
