          Abstract:         In this paper, we discuss consensus problems for a network of dynamic agents with fixed topologies. A consensus algorithm for multi-agent systems with time-varying delay is presented. With the consideration of the effects of network conditions, such as network-induced delays, packet dropouts, mis-sequence, etc., a communication buffer is introduced for avoiding agents¡¯ communication error, and a method for choosing buffer length is proposed. Using this buffer design, received data is rearranged and transferred in the original order. With the presented consensus algorithm, agents¡¯ consensus is well-performance, and all the agents match the average speed finally. Simulation oriented results verify the effectiveness of the proposed algorithm. © (2014) Trans Tech Publications, Switzerland.

          Abstract:         Natural wind, relative position between the nozzle and the outlet of the ram in the air-assistant spray have a great influence on performance. Air-assisted boom sprayer model is developed based on CFD. According to the data of the related parameters of the spray machine, variables of 3-D model were defined. With velocity of natural wind and inlet of the ram, the spraying flow keeping constant, the relative position between the nozzle and the outlet being a research variable, this article calculates the drift rate of the droplets respectively, then analyzes the results scientifically and gets the corresponding conclusion. At the same time, in order to confirm the reliability of the simulation results, this paper makes an experiment, which is done in Shandong agricultural university spray performance laboratory. Studies have shown that drift rate is significantly lower when the nozzles located under outlet position than on the downwind or the upwind. © (2014) Trans Tech Publications, Switzerland.

          Abstract:         Tree-pruning robot can appear tilt problem in the climbing process because of the trunk shape and mechanical mechanism of its climbing legs. According to the robot's tilt problem, this paper guarantees the level of tree-pruning robot using the method of controlling the motor speed at different locations. This paper establishes a three-dimensional virtual prototype model about tree-pruning robot in ADAMS software, design controller in Matlab software, and conduct ADAMS-Matlab co-simulation. The simulation results and experimental prototypes show that the designed control method can effectively overcome the tilt problem in the crawling process. © (2014) Trans Tech Publications, Switzerland.
