Along with the socio-economic development and people's living standards constantly improving, demand for beverages and alcohol increases. Therefore the high-end industrial automatic filling equipment are also promoted. This paper designs and manufactures a liquid filling machine intelligent control system for automated production line of beer. This system is composed by HOLLSYS LM3106A PLC (Programmable Logic controller) and Hollyview industrial control configuration software and Shihlin SS22-023-0.75K inverter composition. We conducted energy dissipation test experiment and canned beer production experiment based on PID control. The experiment proves that the production efficiency of the system has improved the percent of 11.27. Energy consumption of the system has also reduced. So the system which has Advantage of high working efficiency and energy saving can be applied in production in the future.

This paper investigates insensitive Hinfinity control problems for linear continuous-time systems with input and measurement quantization via static output feedback (SOF). The designed controllers are insensitive to additive interval-bounded controller coefficient variations and are made up of two parts as linear and nonlinear parts. The former is used to achieve the Hinfinity performance against external disturbances, unknown initial states and controller coefficient variations. The latter is used to attenuate the effect of input and measurement quantization simultaneously. It should be mentioned that three novel linear matrix inequality (LMI) conditions by using three different methods without introducing a matrix equality constraint as many existing results are obtained. Finally, a numerical example is presented to show the effectiveness and advantages of the proposed methods. © 2015 IEEE.

Due to the increasing concerns about the energy crisis and the environmental problems, electric vehicles (EVs) have been regarded as the future trend. Market penetration of EV has been increasing drastically in the recent years. Large-scale EVs charging has become a practical problem in the grid operation and planning of the distribution network. It might have great impacts on the system performance, such as overloading, reducing efficiency, deteriorating power quality and increasing power system losses. This paper briefly discusses the impact of the charging on the distribution system, the factors of causing the influence and the charging control methods that reduce the impacts on the distribution network.

Diagnosis of potential faults concealed inside power transformers is the key of ensuring power system safety. The existing transformer diagnosis methods only infer based on single informative data and it is difficult to detect transformer faults more correctly. In this paper, fault diagnosis based on multi-class multi-kernel learning relevance vector machine (MMKL-RVM) is proposed which can integrate the informative data that can indicate the existence of fault. MMKL-RVM achieves sparsity without the constraint of having a binary class problem and provides probabilistic outputs for class membership instead of the hard binary decisions given by the traditional SVM. Most importantly, MMKL-RVM enables informative integration of possibly heterogeneous informative data or feature spaces in a multitude of ways, from the simple summation of feature expansions to weighted product of kernels. Additionally, Genetic Algorithm (GA) combined with K-fold Cross Validation (K-CV) method is adopted to optimize the kernels parameters in order to enhance the performance of the MMKL-RVM. Experimental results show that MMKL-RVM is capable of more excellent diagnosis accuracy to BP neural network and SVM.

Space heating accounts for large percentage of building energy consumption, which may cause air quality deterioration in cold climate area. Solar energy systems and ground-source heat pumps are two promising means of reducing the consumption of fossil energy and the emission of green-house gas. Taking a typical office building at tianjin as an example, the application of solar heating system assisted by ground-source heat pumps was studied. The entire system was modelled via the TRNSYS simulation environment and the energy performance was evaluated based on the winter time operation schedule. It shows that the overall system COP can reach 8.17 and the heat pump COP is increased.

This paper covers the concept of smart distribution gird and briefly introduces the necessity to develop SDG from the aspects its social benefits, economic benefits and influence to the distribution grid. As the new forms of the SDG, micro grid (MG) and active distribution network (ADN) are analyzed and compared with each other. Finally, the some technologies and practical problems about SDG are discussed. By incorporating with new technologies like Big Data and Internet of Things, SDG is prone to obtain a new opportunity to develop.
