Abstract: To realize the precise tracking and safe navigation control of the unmanned surface vehicle (USV) in the complex ocean environment, firstly, the line-of-sight (LOS) guidance strategy used in USV trajectory tracking control is studied in detail, and the algorithms are divided into two categories: LOS guidance strategy based on look-ahead distance and on encircling circle. Then, the mathematical model of the USV is built, and the USV trajectory tracking control algorithm is designed based on the LOS guidance strategy using the look-ahead distance and the PID control idea. Finally, the simulation results show that the proposed algorithm has good trajectory tracking control effects, which can provide insights into research on the autonomous navigation control technology and the construction of the USV equipment in China.
