报告题目：Distributed Model Predictive Formation Tracking Control for Autonomous Underwater
Vehicles Subject to Disturbances
内容简介：In this talk, we will introduce the formation tracking problem of a team of autonomous underwater vehicles (AUVs) with the ocean current disturbances. A distributed Lyapunov-based model predictive controller (DLMPC) is designed such that AUVs can keep the desired formation while tracking the reference trajectory, despite the presence of external disturbances. The DLMPC inherits the stability and robustness of the extended state observer (ESO) based auxiliary control law, and invokes online optimization to improve formation tracking performance of the multi-AUV system. The closed-loop stability of the multi-AUV system is guaranteed by the stability constraint that utilizes the ESO-based auxiliary controller and the associated Lyapunov function. Furthermore, the inter-AUV collision avoidance can be achieved by incorporating well-designed artificial potential fields based cost term in the formation tracking cost function. We will show simulation studies on the Saab Falcon AUVs, demonstrating the superior control performance and robustness of the proposed method.
