Multiple Control Surface Coordinated Allocation Strategy for Hovercraft Sailing on Polar Region

Abstract

In order to reduce sideslip and tail flick for Polar Region Hovercraft on snow and ice layer, a multiple control surface coordinated distributed allocation strategy with air propeller, air rudder and bow nozzle is proposed. First of all, a mathematical model for the maneuverability of the hovercraft traveling on ice surfaces is established, and the tail swing characteristics of hovercrafts traveling on ice and snow surfaces are obtained. Then multi-surface coordinated control allocation is realized with air propeller for speed control, air rudder for heading control, and bow nozzle for sidelip control. Finally, simulations for hovercraft turning on ice surfaces are carried out to valid the effectiveness of the control allocation strategy.
