High Precision Height Control for Wing-in-Ground Crafts

The wing-in-ground effect craft (WIG craft) is a kind of vehicle that flies close to the ground achieve flight with low aerodynamic drag and high lift. A robust precise height control system essential ensure small WIG crafts fly safely in effect. In this paper, performance different precision systems based on PID controllers investigated numerically altitude disturbances. results show operates throttle, elevators, flaps aircraft (TPF system) minimum overshoot, undershoot, rising tine, settling time recovering from disturbed altitude, fluctuation pitch angle. Compared TPF system, even though throttle (TF has longer higher it smaller oscillation angle during altitude. addition, operating helps reduce change velocity disturbance. Furthermore, simulation little influence systems.
