Motion performance and control method for polar region hovercrafts with multiple control surfaces

Abstract

We establish an ice surface kinematics model of polar region hovercrafts for the analysis of the motion characteristics and control difficulties of polar region hovercrafts to study the motion characteristics and coordinated control methods of polar region hovercrafts with multiple control surfaces on snow and ice layers. We propose motion control architecture of polar region hovercrafts with multiple control surfaces, realizing coordinated distributed control on six control surfaces of the air propeller, air rudder, and vectoring nozzle. Simulation results demonstrate that polar region hovercrafts are prone to sideslipping and tail flicking under crosswind conditions. Our method can effectively solve the problem of the course stability control of hovercrafts during polar region maneuvering. Dangerous sideslip motion is well suppressed by vectoring nozzles. The crosswind resistance curve of polar region maneuvering is obtained by analysis. Our method provides an effective and feasible solution for the research on motion control technology and safety control strategies of hovercrafts in Polar Regions.
