Considering nonlinear behaviors and environmental disturbance of the boiler pressure control system, a linear interpolation fuzzy controller is developed. First, according to the conventional discrete fuzzy control principle, a discrete fuzzy controller for the system is designed and a 2-D fuzzy control lookup table is deduced. Then, to overcome the conventional fuzzy controller's disadvantage of lower precision caused by discretization, a bilinear interpolation 2-D table lookup method is used to replace the exact lookup method, with which continuous output can be obtained from the discrete control table. Finally, based on the existed computer control system and boiler system hardware configuration, hard-in-loop real-time simulation system is established in Matlab/RTWT. Lots of experiments are carried out. And the results prove that better control performance can be achieved with the proposed control scheme. © 2013 IFAC.

Mechanism analysis and simulation of coplanar multi-electrode capacitive ice thickness measuring sensor

Sensors and transducers 2013年第11期158卷 27-32页

作者： Yinke, Dou Xiaomin, Chang College Electric and Power Engineering of Taiyuan University of Technology 030024 Tai Yuan China Key Laboratory of Advanced Transducers and Intelligent Control System Ministry of Education Taiyuan 030024 China

In this paper, we use the coplanar multi-electrode for designing a rod-shaped sensor for measuring the ice thickness. In order to analyze and study mechanism and feasibility of ice thickness measurements using this technique, we use modes of mathematical model derivation and software simulation to study coplanar multielectrode capacitance sensors. It uses MAXWELL software to simulate the coplanar multi-electrode capacitance sensor under the models which are being approached by three different media, namely ice, air and water. Both mathematical model derivation and simulation results show that the sensor designed with coplanar multielectrode capacitance can be used to level the automated measurement of sea ice or river ice thickness. The accuracy is ± 1 cm. © 2013 by IFSA.

Excavator Energy-saving Efficiency Based on Diesel Engine Cylinder Deactivation Technology

Chinese Journal of Mechanical Engineering 2012年第5期25卷 897-904页

The hydraulic excavator energy-saving research mainly embodies the following three measures： to improve the performance of diesel engine and hydraulic component, to improve the hydraulic system, and to improve the power matching of diesel-hydraulic system-actuator. Although the above measures have certain energy-saving effect, but because the hydraulic excavator load changes frequently and fluctuates dramatically, so the diesel engine often works in high-speed and light load condition, and the fuel consumption is higher. Therefore, in order to improve the economy of diesel engine in light load, and reduce the fuel consumption of hydraulic excavator, energy management concept is proposed based on diesel engine cylinder deactivation technology. By comparing the universal characteristic under diesel normal and deactivated cylinder condition, the mechanism that fuel consumption can be reduced significantly by adopting cylinder deactivation technology under part of loads condition can be clarified. The simulation models for hydraulic system and diesel engine are established by using AMESim software, and fuel combustion consumption by using cylinder-deactivation-technology is studied through digital simulation approach. In this way, the zone of cylinder deactivation is specified. The testing system for the excavator with this technology is set up based on simulated results, and the results show that the diesel engine can still work at high efficiency with part of loads after adopting this technology; fuel consumption is dropped down to 11% and 13% under economic and heavy-load mode respectively under the condition of driving requirements. The research provides references to the energy-saving study of the hydraulic excavators.

Using computer vision technique to detect coal level of coal bin, a kind of non-contact depth measurement method of coal bunker was put forward based on binocular vision and W-SIFT image feature matching algorithm. Through the wavelet compression coding and scale invariant feature transform algorithm, remove all kinds of redundancy in image and keep important information. By adaptive regulating based on template of the changing scale factors and dealing with the coal bit image waiting for the binocular view registration, multi-scale spatial could be created for extracting feature points in coal level image. The left and right view is compared, and extraction feature points for in-depth matching based on the bidirectional registration strategy of binocular view so that we can more accurate restore the 3D information. According to the W-SIFT matching algorithm, prior calibration left and right image so that we can get internal and external parameters of visual sensor, then, determine the coal bunker coal bit depth value based on the coordinate transformation formula. Using the new algorithm to detect coal level, The result is satisfy compared with the traditional SIFT algorithm.

The electrical characteristic test of nanowires is important in nano-materials research. The metal-semiconductor junction that is fabricated with semiconductor nanowire and metal probe in electrical test system has impact on the test result directly, therefore it's necessary to study I-V characteristics of the metal-semiconductor(M-S) junction. Si, ZnO, GaN have been selected from multiple semiconductor materials. When they connected with tungsten probe, all of them formed Schottky barriers, but the relationships between current and voltage of the junctions are distinct. In the thesis, I-V curves of these M-S junctions are compared, and the best electrical performance of M-S junction is selected.

Recently biosensors based on silicon nanowire field-effect transistors (SiNW-FETs) have drawn huge amounts of attention, due to their ultra sensitivity, selectivity, label-free and real-time detection abilities. As people know more and more knowledge of the structure and function of nucleic acid molecules, DNA detection has gained importance increasingly. Here, we briefly summarize major fabrication methods in synthesising SiNW-FETs and selectively describe some applications of SiNW-FET biosensors in DNA detection over the past few years. Some key results from each article are summarized, involving the concept and mechanism behind each sensor, with the aim of stimulating more efforts in developing SiNW-FET biosensors for detecting DNA.
