Design of information network and control system for USV

The technology of information network and control system for unmanned surface vehicles (USVs) is one of the most important USVs´ research areas. By analyzing of the data and information which collected from various devices and sensors on the USV, a kind of the USV control system that can meet the needs of various tasks is designed. Based on characteristics of sensors data´s obtainment, transmission and control systems, the architecture of information network and control system for the USV is built with the combination of NMEA2000 protocol, Ethernet and wireless communication network. At the same time, the tasks division, the decision control process and the control algorithm simulation of the USV are descripted in detail. Finally, a kind of fuzzy self-adaptive PID control algorithm for the USV course control is put forward. With the disturbances of wind, wave and current, simulation results show that fuzzy self-adaptive PID course control algorithm has good dynamic response performance for the USV, and it also has good robustness to the parameter perturbation and external disturbances.
