Abstract: In recent years, the import and export scale of auto parts industry grows increasingly in Jilin Province. According to the index of intra-industry trade of auto parts, the intra-industry trade level of the Jilin Province’s auto parts is relatively lowly, there are a great of room for development. In order to enhance the level of intra-industry trade, the enterprises should promote the upgrading of the processing trade, improve the quality of imports, take the independent brand and intellectual property rights as the key, to enhance the export competitiveness. The auto parts enterprises must shift gradually to the plurality of supporting activities from the original single production activities.

Abstract: Iron & steel industrial circulating water system there is a scaling and corrosion problems, the system fouling or corrosion may be judged by monitoring the water quality Stability index. In this paper, we use the magnetic treatment equipment developed by us in the laboratory to simulate the physical treatment process of magnetic field on the industrial circulating water system, and the experimental data is analysis by two-way ANOVA. We have found that: when the circulating water is tap water: (1) if water velocity is 0.6m/s, the magnetic field intensity, magnetic treatment time has a significant influence on the PSI, PSI decline with the magnetic field processing time to increase , and the PSI as well as the time have a good linear relationship; (2) if water velocity is 1.2m/s, the magnetic field strength has a significant influence on the PSI; (3) if water velocity is 2.3m/s, the magnetic field intensity and time has a significant effect for the PSI; when the magnetic field strength is 3.4T, and reaction time is 5 h, PSI is close to 6, water quality is stable; (4) speed and the magnetic field there is an interaction for PSI, that the magnetic field strength and speed of circulating water changes in the PSI also. When the circulating water is CaCl2 and Na2CO3 aqueous solution configuration: as water velocity is 1.2m/s and well as 2.3m/s, the magnetic field strength and time has a significant effect on the PSI .The results show that: iron & steel industrial circulating water system be deal with by proper the magnetic field treatment can control the PSI. The appropriate range PSI of the circulating water can reduce the fouling and corrosion damage, it is significant to develop circulating water system quality control model.

Abstract: The former research on the overload control system of a supersonic missile didn’t consider actuator saturation. In order to reduce the windup effect caused by actuator saturation, we developed a dynamic anti-windup compensator. The overload control system design adopted a two-step approach. Firstly a sliding mode controller was designed ignoring the saturation. Secondly a dynamic anti-windup compensator was designed. It added to the control system to reduce the windup effect. It disengaged the actuator fast from saturation phase after the actuator entered saturation. Simulation results showed that the dynamic anti-windup compensator reduced 52% of saturation time of the control system. Hence the performance of the overload control system is improved effectively.

Abstract: The aim of this paper is to show how to apply TRIZ to resolve conflicts in management area, especially in product life management (PLM) in desinging and manfacturing smart-phone. TRIZ has been well-known as a creative and innovative thinking theory in solving engineering and technology contradictions in the last two decades. However, few studies and practical usage were proposed in management area. Conflicts occurring in product life management including schedule, budget, and risk ones at smart phone R&D process are discussed to demonstrate the ideas guided by 39 TRIZ management parameters, 40 TRIZ innovative principles, and contradiction matrix. The results show that TRIZ is able to provide direct, quick and effective alternatives to resolve the conflicts in PLM. In this manner, huge effort and cost can be saved in further project execution stage. In this paper, an innovative 3C consuming product such as smart-phone is utilized as a case study to describe the proposed TRIZ-based conflicts-solving approaches at PLM stage.

Under this case, this paper introduces a design of a data collection system that is transparent and controlled by the host computer. It uses a data acquisition system software design model which will help in speeding up the development of the system, reducing maintenance costs as well as improving data collect velocity. This paper describes the data acquisition system based on ARM hardware platform, its software framework and design process.

Abstract: In this paper we propose an intelligent adaptive retrofit reconfigurable controller in which the full system states are reliably measurable and available for feedback and diagnosis. The proposed approach retains the existing nominal controller and adds a suitably chosen signal that assures that the desired closed-loop performance is achieved despite the failure. The approach is based on the properties of the system controlled by the nominal controller, and judiciously chosen adaptation signals. Furthermore, some representative methods of intelligent reconfigurable control are introduced, especially intelligent fault diagnosis and intelligent reconfigurable control strategies based on adaptive neural networks and fuzzy reasoning has been discussed in details, which has ensure that the aircraft has retain its flying qualities to a satisfactory level even to the presence of severe control failures. The ability to control aircraft is shown through simulation results with the intelligent reconfigurable controller using the adaptive fuzzy-neural reasoning of the aircraft.

Abstract: This paper mainly talks about the design of a controlling and monitoring system of the robot arm based on FPGA. The robot arm has 6 DOFs (Degree of Freedom). Every joint was driven by a servo motor. These servo motors were located as the finger, the wrist, the three arms and a rotatable platform. The FPGA programs were completed using the Verilog HDL. We programmed a LabVIEW VI to function as a controlling center. The data between PC and FPGA were transported through a ZigBee wireless network which consisted of 2 XBee devices and a wireless camera. They were used to monitor the moving condition of the arms. The experimental results show that the robot arms move with no apparent delay controlled by the host computer. The real-time display of the arm’s status is realized by the upper computer.

Abstract: The inverse design of air-to-air missile system was researched according to its target performance database. Firstly the initial model and database of air-to-air missile were set based on a foregone and similar missile model which includes the database of aerodynamic coefficients, engine performance, mass properties, guidance law and so on. Then this initial model and database were optimally modified by using the improved elitist preserved genetic algorithm and flight simulation based on the 4-D motion differential equations of both the air-to-air missile and target vehicle. The inverse design algorithm globally minimized the performance errors which were obtained from the inversely designed envelopes compared with the desired target performance database of maximum intercept envelope and the maximum impossible escape (no-escape) envelope. The optimized numerical simulation results of inverse design are showing that both the average error and the maximum error of missile envelopes are very small and can be acceptable, which verified that the inverse design algorithm of system is high accuracy and reliable.

Abstract: This paper constructs a closed-loop supply chain system with the manufacturer recycling waste products from the retailer based on game theory in heterogeneous market in which the price of the new product is different from that of the remanufactured product. The optimal pricing decisions of the supply chain without remanufacturing and the closed-loop supply chain with remanufacturing are obtained. Through theoretical analysis and numerical simulation, we obtain the optimum production and pricing strategies, and analyze the impact of the consumers’ acceptance for the remanufactured product on product pricing, which provides a basis for the closed-loop supply chain’s production decisions.
