Abstract: This paper presents a strategy of formation generation and formation transformation for multiple unmanned surface vehicles (USVs) in narrow waters. In order to solve the problem of multi-USV transformation in narrow waters, priority model and virtual intermediate goal are adopted. Multi-USV formation can successfully pass narrow waters while maintaining its shape by using this method. The formation generation and transformation are controlled by back-stepping based sliding motion controller (BSMC). The combination of back-stepping method and sliding motion control can deal with the uncertainty of mismatch, ensure the real-time performance of control and is easy to deploy on the actual USV. The simulation results show that the method enables the formation change quickly in narrow waters, makes the formation pass smoothly, and the error converges to zero in finite time.
