Abstract:

Offshore commissioning for unmanned surface vehicle (USV) is costly, difficult and inefficient. To reduce the workload of sea tests, a simulation system is designed for test and analysis of USV control systems, and a simulation process is programed. The simulation system includes five modules. The display and control module is used for global path planning and comprehensive information monitoring. The data simulation module simulates data of sensors for obstacle detection and positioning. The obstacle process module preprocesses, rasterizes, clusters and fits the detected data, and tracks moving obstacles. The navigation and obstacle avoidance module is made of line of sight (LOS) and an elliptical clustering-cone deduction algorithm. The cascaded generalized predictive control-proportion-integral-derivative (GPC-PID) method is used in the motion control module. Every simulation module is independent, and can be switched according to different requirements. The simulation results show that the described design of the simulation system for USV is accurate and reasonable.
