But in fact, the system of half-tracked air-cushion vehicle is over complicated. When the vehicle drives in an unknown soil, the parameters and structures of controlled member will change with load or disturbances. This system is nonlinear and time-variant, and it is very difficult to analyze its transfer function and state function quantitatively.

In order to prove the reliability, test studies have been primarily carried out in the indoor soil bin. The data of the vehicle driving state parameters under the same or different terrain are analyzed. The process curves are compared by different control schemes. The theoretical model of the optimum driving state is reliable and fuzzy control scheme is feasible. The disturbances and unknown factors of control system are analyzed. Test results prove that the half-tracked air-cushion vehicle can drive steadily under control of the computer. At the same time the sensors used to measure soil mechanics characteristics on line need to be developed. And it is the important problem to be solved in the future study. The necessary regulation and correction are put up. So the studies in this paper provide some instruction for the further research work.
