Some Autonomous Underwater Vehicles have recently been designed to mimic the locomotion of underwater animals. A new way of propulsion which uses Oscillating Fin Thrusters (OFTs) has been implemented on the AUV Morpheus, with the Nektor module. In particular, first a low level adaptive controller has been developed with the purpose of studying the characteristics of the OFT. Then, a new vehicle using Morpheus' base has been built in order to implement this module and test it. This required...
Show moreSome Autonomous Underwater Vehicles have recently been designed to mimic the locomotion of underwater animals. A new way of propulsion which uses Oscillating Fin Thrusters (OFTs) has been implemented on the AUV Morpheus, with the Nektor module. In particular, first a low level adaptive controller has been developed with the purpose of studying the characteristics of the OFT. Then, a new vehicle using Morpheus' base has been built in order to implement this module and test it. This required for the Lonworks network to be interfaced with QNXnet to create a multi communication protocol vehicle. Concerning the high level control, some proportional controllers and a 6-degree of freedom adaptive controller have been implemented and tested on the new vehicle. The results from these tests have shown that the Nektor module is suitable for the Morpheus, providing high-maneuverability features unavailable when using more standard propulsion systems.

This thesis describes the development of a simulation environment for Autonomous Underwater Vehicles (AUVs) on UNIX platforms. AUV missions can therefore be carried out without going to the sea. The Yoyo controller, a component for AUVs is also described in this thesis. The main function of Yoyo is to control the vertical profile of an AUV while it is navigating underwater performing data collection missions.

Several test cases have been performed, and the test results have clearly demonstrated the successful development of the controller.

- Abstract/Description

Autonomous Underwater Vehicles (AUV) rely on acoustics for a number of mission functions such as communications (Acoustic Modem) and vision (Forward and Side Looking Sonars). The AUV acoustic signature (self-noise and vibration) can thus interfere with AUV operations. Additionally, underwater measurements such as turbulence measurements can be contaminated by interference between the AUV generated acoustics pressures and the low pressures of the turbulence.

Show moreAutonomous Underwater Vehicles (AUV) rely on acoustics for a number of mission functions such as communications (Acoustic Modem) and vision (Forward and Side Looking Sonars). The AUV acoustic signature (self-noise and vibration) can thus interfere with AUV operations. Additionally, underwater measurements such as turbulence measurements can be contaminated by interference between the AUV generated acoustics pressures and the low pressures of the turbulence. In this thesis a Finite Element and Boundary Element approach is developed to characterize the self-noise (vibration and radiated sound pressure) of a simplified FAU Ocean Explorer AUV. Mechanical excitation from the "podule", which contains the motors for the propulsion and motion control, is assumed in the analysis. The low frequency (less than 1Khz) results are dominated by two types of modes. One type associated with the motion of the "podule" as a rigid body on the vibration isolation supports that connects it to the rest of the AUV structure. The second type is associated with local structural deformations of the "podule", support frame, and AUV hull. Modifying the stiffness of the supports reduces the frequency of the rigid body modes of the "podule", but does not influence the frequencies of the local structural deformations of the "podule" and the rest of the AUV. Decreasing the stiffness of the supports should result in a reduced AUV acoustic signature.

Show moreThis thesis describes a new Inertial Navigation System (INS), designed for use on the latest generation of Autonomous Underwater Vehicle (AUV), the Morpheus AUVs, developed by the Department of Ocean Engineering. The INS makes use of a high precision Inertial Measurement Unit (IMU) along with a Doppler Velocity Log (DVL), a GPS/DGPS system and a flux gate magnetic compass to estimate the position of the vehicle during a mission. Extensive data processing methods are used in order to reduce the sources of error most critical to the navigation estimation. Accelerometers and gyroscopes are used to estimate the vehicle attitude in a complementary filter; a standard Kalman filter performs yaw rate bias estimation, whereas a second, extended Kalman filter, provides position estimation of the vehicle in real time, while also correcting for heading errors. Overall the INS is capable of providing the Morpheus with 1% navigation accuracy over an hour.
