Research Abstract

An AUV which could be operated both as a cruising type and an exact automatic position control type vehicle would be most advantageous for ocean measurement. But it is difficult for an AUV to have both these functions, because the hydrodynamic characteristics and control method required for the two types of vehicle differ greatly. A quarter size model vehicle named "Diving Beetle" was developed for this study. The principal dimensions are; length:1.2m, width:0.7m, height :0.24m, weight in air:40kg. The vehicle has 6 thrusters and 2 horizontal tail wings to control the motion. The vehicle is used only in the ocean engineering tank (L:65m, B:5m, D:7m) to study motion control. If communication between the vehicle and a personal computer were possible in real time, we could set the PC in the laboratory on the towing carriage of the tank. This system could reduce the volume, weight and battery power of the vehicle. Moreover, in this system, it would be very easy to change the PC system (PCs are evolving daily.). "Diving Beetle" communicates with the PC using a digital proportional radio control system of a model aircraft.
The experiments to measure the hydrodynamic coefficients of the vehicle were carried out in the ocean engineering tank, and the equation of motion was constructed. This equation was used for the design of the controller and motion simulation.
The model based controller, gain scheduled controller and neural Network controller were studied to control the motion of the vehicle.
