Underwater vehicle is an important tool in the exploration, survey and investigation of the ocean and have many scientific, military, and commercial applications. To develop an underwater vehicle is not an easy task; a reliable underwater vehicle requires a thorough system design and many costly field tests during which system specifications can be validated, and these field tests can be hard and...
In order to fulfill high accurately control of HOV' dynamic positioning on the condition of multiple uncertainties, and overcome the guarantee of the H∞ robust controller, a robust controller based on structure singular value theory was designed for deep sea HOV. Dynamic positioning test and comparison test between difference control arithmetic were carried out on the semi-physical simulation platform...
ARV is a new concept unmanned underwater vehicle (UUV) which has both the characteristics of autonomous underwater vehicle (AUV) and that of remote operated underwater vehicle (ROV). It is a hybrid ROV/AUV. ARV can cruise at a range of 3km at the speed of 3kn, in a depth shallower than 500 meters. At the attractive point the vehicle can be operated as a ROV with the ability of dynamic positioning...
This paper presents a simulator to simulating two key problems-underwater perception and autonomous manipulation o In the simulator a controller-observer strategy is proposed. A new SLAM (Simultaneous Localization and Mapping) algorithm - UKF (Unscented Kalman Filter) is used to estimate the state of UVMS (Underwater Vehicle Manipulator Systems) and the target object. 3D Simulation results show that...
A semi-physical virtual reality system applying to MSV (manned submersible vehicle) control study is presented in this paper. This system is composed of three nodes: (1) control node for receiving sensors information and sending control command, (2) virtual sensors node for virtual devices and sensors and (3) Visualization node for virtual ocean environment and displaying the posture of MSV. The control...
