	Abstract:Sea water temperature is a physical quantity that represents the thermal state of the ocean. Depending on the state of the ocean thermal budget and time, the ocean temperature field will periodically or irregularly change with time. Current research on ocean temperature fields is mainly focused on marine fishing, aquaculture, etc., or research on specific sampling and reconstruction methods of sea temperature. From the perspective of the practical application of underwater vehicle equipment, this paper studies the display method of ocean temperature field data. Compared with the current device that displays the temperature field information change pattern by curve values, the three-dimensional visualization method can more intuitively and effectively describe and describe the current state of the temperature field environment in the sea area, and improve the commander's understanding and application of the temperature field as a whole Making tactical decisions provides reliable technical support, so it has broad prospects in practical engineering equipment applications. This paper analyzes the seawater temperature field data characteristics and sampling methods, uses ray projection volume rendering method to realize three-dimensional display of the ocean temperature field, and encodes data classification, coordinate conversion, and resampling specific processes.

	Abstract:By analyzing operating principle and topology structure, complex water supply network can be abstracted into a weighted directed graph. Using Dijkstra algorithm, minimum dissipated power paths from water sources to all nodes have been calculated to simplify the original network. Combining Sugiyama algorithm, the main network layout with a hierarchical structure and initial District Metering Area can be defined. For those nodes who are far away from the water sources and close to the border area, a boundary criterion has been proposed to check the belongings and to determine the final District Metering Area partition. Finally, a sample town with real data in InfoWorks WS software has been set up. This case study is presented to illustrate the effectiveness of our proposed method

	3. Application of PID Controller based on Improved BPNN in the Magnetic Inertial Measurement System
	LI Deqiang,ZHANG Yangan

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:To adapt slow time variation of the hardware parameters and nonlinearities in Magnetic Inertial Measurement System (MIMS), the improved Back Propagation Neural Network (BPNN) algorithm is effectively integrated to the traditional PID controller. BPNN has the ability to represent any nonlinear functions, which can achieve the best combination of PID three coefficients in real time online learning. Using BPNN can help to build the coefficient self-learning PID controller in MIMS. The simulation which was established in MATLAB indicates that the improved BPNN PID controller can improve the robustness of system and has high accuracy control. At last, experiments in MIMS convincingly verified the simulation.

	4. Nonlinear consensus protocol design for multi-agent systems under directed topology
	XU Yaojin,TIAN Yuping
	Electrics, Communication and Autocontrol Technology 06 January 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, the problem of consensus of multi-agent systems is investigated, and a framework for the nonlinear protocol design is proposed. First, the block cascade property of the information flow is demonstrated via the decomposition of the directed communication graph. Then, the interactions among different agent groups are described by means of the input-to-state stability theory. Within the proposed framework, multi-agent systems with single-integrator dynamics are particularly investigated with a class of nonlinear protocols. Finally, numerical examples are provided to show the effectiveness of the designed protocol.

	Abstract:When executing a complex mission, the multi-AUV system need to confirm a better task allocation scheme to make sure that the system is efficient. However, there are many standards which are utilized to determine the system's efficient, and there maybe confliction between them. In order to solve the task allocation of multi-AUV system based on multi-objective optimization, a multi-objective optimization based on ant system algorithm was proposed. By the single-objective optimization in single ant system and the interaction between different ants systems, this algorithm achieve the Pareto solution's set at last. On the other hand, an algorithm evaluation method was given out to evaluate the performance of the algorithm above. Based on this algorithm, the task allocation of multi-AUV system based on multi-objective optimization was studied in details and the stimulation of task allocation was provided.
