MANEUVERING CONTROL OF AMPHIBIOUS HOVERCRAFT

The response of an amphibious air cushion supported vehicle or hovercraft during turning maneuvers with and without an automatic control system is examined. Over water response is predicted by a digital simulation program in which the plant model is based primarily on experimental model data. A digital simulation model is also used to study over land response. However, in this case, an analytical model is used for the plant. The results indicate significant overshoot and settling times in response to turn rate demand. By performing a gain sensitivity study it is demonstrated that improvements in craft response can be realized by using a speed dependent gain scheduling strategy.
