Event-Triggered Finite-Time Course Control for Unmanned Surface Vehicles with Quantization
2024 IEEE 33rd International Symposium on Industrial Electronics (ISIE)(2024)
Abstract
This paper concerns the event-triggered finite-time course control problem of an unmanned surface vehicle (USV) under the network environment. To facilitate investigation, the nonlinear dynamic of the course control system is firstly modeled by a class of state-dependent uncertain systems. Then a output feedback framework of course control is established for the USV subject to wave-induced disturbance, where an event generator with dynamic triggering scheme and a logarithmic quantizer are introduced to save communication resources. By means of slack variable technique, a novel co-design criterion of output feedback controller and event-triggered scheme is developed to guarantee the course control system finite-time bounded with a desired ${\mathcal{H}}_{\infty}$ performance. Finally, the effectiveness of the proposed method is verified through a practical simulation case.
