As a special device of air cushion vehicle, cushion system can reduce sailing resistance deeply so as to obtain higher speed. The main drawback is that sideslip phenomenon occurs easily, especially in the turning process. To solve this problem, a robust course controller for ACV is designed based on terminal sliding mode control method. The designed controller is more effective under the influence...
This paper addresses the problem of steering an underactuated hovercraft along a desired horizontal path in the presence of dynamic uncertainties. First, based on the predefined reference path, the Line-of-Sight (LOS) guidance is built in a moving Serret-Frenet frame along the virtual target on the path. The position and orientation error dynamics are introduced by using coordinate transformation...
This paper analyses the force of the landing gear during the process of taking off and landing of the aircraft on six-DOF platform, and simulates the running of the system. Most studies of the landing gear models are based on the steady ground. In this paper, the model supports for anomaly. Applying dynamics basic theory and considering the impact of various parameters as much as possible, it establishes...
