Abstract:
The dynamics and control of nonlinear models of supercavitating vehicles are considered. Cavitation
is the physical phenomenon of bubble formation in a liquid subject to local pressure variations. Super-
cavitation is an extreme form of cavitation in which a single bubble almost completely envelops the
moving vehicle. Due to the reduced drag forces associated with a supercavitating body, dramatic
speed increases can be realized through introduction of supercavitation. Cavitation occurs when a
certain quantity, the cavitation number, is below a critical value. However, to achieve supercavitation
and controlled vehicle dynamics, a device known as a cavitator is incorporated into the vehicle nose
to introduce a gas around the vehicle at speed. Moreover, the system dynamics involve significant
