In view of the problems existing in the teaching links, the practice teaching platform of unmanned boat engineering control course is developed with the computer technology and industry software. The Unmanned Surface Vessel (USV) modeling and trajectory control can be conducted on the platform. In view of the uncertainty of USV physical parameters, the controller is designed according to the kinematics models and dynamics models, and the influence law of controller parameters on USV motion performance is analyzed. The construction and application of practice teaching platform of unmanned boat engineering control course can improve the ability of students in motion control, fault judgment, and maintenance of USV.
