According to the problem that pitching angle control of underwater glider is strongly influenced by wave and current, so we use the phase-lead compensator as a guide which can achieve the optimal control effect. This study aims to find one of the most suitable control methods for underwater glider to improve the effect of movement. Experiment shows that control system have obviously improved in terms...
Underwater glider is a long-range autonomous underwater vehicle for oceanographic research that propels them through the ocean by changing their buoyancy. Balance parameters usually obtained through experiments. These kind of inaccurate parameters have a great influence on gliders gliding. In this article, a balance parameters calculation method of underwater glider based on BP neural network is presented...
This paper proposes a compact DC-DC buck converter with low output power and very low quiescent current dissipation for use in an ultra-capacitor based wireless sensor networks (WSNs) nodes. This converter is controlled by a self-oscillation topology in order to achieve less silicon area and lower quiescent dissipation than the conventional designs. The work is implemented in the standard 0.35um CMOS...
Substation inspection has already benefited from developments in mobile robotics. Since 2002, over 10 substation inspection robots have been developed at Shandong Electric Power Institute. These robots carry visible light cameras and infrared thermographs which are used to detect invaders and equipments fault respectively. They move inside the substation and position for collecting images of possible...
This paper describes the development of a patrol robot for the detection of equipments fault inside an electric power substation. The robot, carrying an infrared thermograph, automatically moves around the substation and positions for collecting images of possible critical points. It is fully featured with autonomous navigation, autonomous battery charging and autonomous equipments recognition. It...
