Amphibious hovercraft course control based on adaptive multiple model approach

Resistances exert on the hull is changing erratically when an amphibious hovercraft sailing. So it is necessary to study nonlinear control means for amphibious hovercraft course control. Adaptive multiple model approach was applied to hovercraft course control. Multiple model sets were established, and work points were divided according to ship speed. Local controllers were designed for each work point, and switch rule bases on weighting methods. Course control simulation tests were done. Results show that adaptive multiple model approach is better than conventional control as for hovercraft course control.
