In order to improve the success rate of a soccer robot shooting a goal a new method of shooting action control based on genetic-fuzzy algorithm is presented in this paper. An MIMO fuzzy logical controller is established and the soccer robot is controlled by a set of fuzzy rules to complete shooting action in a real-time environment. To establish an optimum fuzzy logical controller a genetic algorithm is used to optimize the fuzzy rules and membership functions so as to increase the ability of the fuzzy logical controller to respond rapidly to the changes in the dynamic environment. We also take the kinematics model of wheeled mobile robot into account and use the speed of wheels directly as the output of fuzzy rules. Experimental results in simulation and vision-based remote brainless soccer robot system prove the method is correct and feasible.

The method of machining Al6061-T6 with large strain to produce nano-materials was introduced, and the influence of cutting parameters on the microstructure was studied. The shear strain of chip which is important to the microstructure was analyzed theoretically and simulated by finite element. Bright-field TEM images and SAD patterns were obtained and used to study the microstructure of the chip. The result shows that, the shear strain of the chip worked by simplified formula is similar to the result of finite element simulation. The size of the grain of chip is reduced when the shear strain increased and the fine grain less than 100nm can be obtained when the shear strain is large enough.

With development of modern industry, more and more non-linear loads are used in power system, resulting in increasingly severe harmonic pollution. Harmonic becomes main factors affecting power quality. Active power filter, as the most effective method to eliminate harmonic, has been paid more and more attention recently. The current compensation performance of active power filter depends on the controller. At present, more and more active power filters have been controlled by digital controller, which has the advantage of flexible control strategy, powerful ability of signal processing. However, digital controller has inherent drawbacks, such as quantization error, signal delay caused by Zero-Order hold, sample and computation delay. With analyzing active power filter's decreased performance caused by digital controller, this paper concentrates on two reasons: Zero-Order hold, sample and computation delay.

Underwater welding repair in nuclear power stations is usually carried out by diving welders, with features of great dangers and uncertainty of joint quality. An innovative automated underwater local dry MIG welding system is developed, and may be applied to take the place of underwater welders in nuclear power plants repair. Underwater welding test chamber is built to simulate 30 meters water depth, the chamber is a large vertical pressure vessel with a hydraulic driven cover and three viewing systems, to obtain images from surface, welding arc and underwater. Remotely eperated underwater welding equipment is a three-dimentional platform, also driven by hydraulic servo valves, to realize travelling, oscillation, and vertical adjustment needed by welding. Argon is transferred into the shielding cup, to drive water from the cup bottom and build a local dry space around the welding gun. Welding test of 304 stainless steel under 15 meters water depth are carried out, perfect NDT and mechanical test results are obtained. The remotely operated underwater welding technologies will contribute to the progress of nuclear power plants repair.

In order to analyze the characteristics of the transcritical CO2 heat pump system with throttle valve, it is necessary to simulate and further to optimize control the system operation. Therefore, the mathematical model for this system is developed in this paper. The simulation values are validated by the test data. The results show that the average error for cooling coefficient of performance (COP) and heating coefficient of performance (COPh) between simulation and experiment values is 10% or so. Then with the validated model, system performance is simulated for various operating parameters. Decreasing the inlet temperature and increasing the mass flow rate of cooling water both can increase the system performance. Whereas, increasing the inlet temperature and mass flow rate of the chilling water is slightly favorable. Compared to other parameters, the effect of water temperature at the inlet to the gas cooler on system performance is more significant. At last, the high pressure control strategy is introduced since there is an optimum high pressure corresponding to the maximum COP.

The training samples, verification samples and testing samples that the model needed were generated by the randomly get arms method in the range of single-index evaluation standard. The case study indicates that the methodology for generating samples and the process for establishing BP-ANN model are effective and reliable. The phenomenon of over-training and over fitting can be effectively escaped, the model possesses good generalization. Comparing to the methodology of Fuzzy theory, the influence by personal factors can be escaped.
