Abstract: New flue-curing process which can accommodate new curing barn which temperature and humidity can be auto-controlled was studied. Based on results of the study on new curing barn and the baking theory, the flue-curing process for new curing barn was programmed. Flue-curing results of this new curing process for new curing barn were compared to the results of conventional baking process for conventional barn. The comparison result was that the new process was simple, convenient and easy-running. The quality of cured tobacco leaf from new curing process was improved: proportion of orange tobacco leaf, the first class tobacco leaf and the first/secondary class leaf was improved by 3.38, 4.74 and 2.03 percentage respectively than the value of conventional process. Meanwhile, the value of total sugar, starch, nicotine, total nitrogen, protein and the difference between total sugar and reducing sugar were lower than the result of conventional process. Chemical composition was more balance than conventional process.

TTCAN bus line on average delay modeling analysis, through analyzing the TTCAN bus line average delay modeling analysis, using computer simulation tools, creates a transport simulation model TTCAN bus.

Abstract: This paper investigates the problems of stability analysis and stabilization for a class of switched fuzzy discrete-time systems. Based on a common Lyapunov functional, a switching control method has been developed for the stability analysis of switched discrete-time fuzzy systems. A new stabilization approach based on a switching parallel distributed compensation scheme is given for the closed-loop switched fuzzy systems. Finally, the illustrative example is provided to demonstrate the effectiveness of the techniques proposed in this paper.

Abstract: An intelligent control system for Differential Reactor is proposed based on the intelligent visualization control system, in order to reduce the complexity of process and temperature control during the operation. The Man-Machine Interface Unit is developed based on touch human-machine interface, this unit can be used to monitor and test the change of the parameters during Differential Reactor operation. At last the unit in combined with the Fuzzy PID-type controller. The practical tests performed in this article show that the new system can monitor the Differential Reactor in real-time, can effectively improve the visibility of the production process, simplify the system control, and effectively reduce the system failure rate.

Abstract: Nowadays intelligent vehicles play a more and more important role in daily life. In this paper, a track-hunting intelligent car is presented for intelligent control research. In the direction control of this car, a fuzzy Proportional-Integral-Derivative (PID) controller is applied to make a distinction between different situations and execute self-tuning operation at the same time. The controller is tested by simulation and experiments in this paper, and results prove effectiveness of the controller.

Abstract: In order to prolong the service life of the battery, ensure the operation efficiency of photovoltaic energy storage system, the establishment of a complete set of battery energy management strategies for photovoltaic energy storage system is very necessary because of the intermittent of solar energy. A strategy based on the state of charge of the battery to realize energy management strategy for photovoltaic energy storage system is proposed in this paper. The simulation verifies the effectiveness of the proposed method and the results show that the method can realize the purpose better.

Abstract: In this paper, ARM processor and real-time embedded operating system will be used in controlling system of sewage disposal, compared with the traditional controlling system of sewage disposal online PLC, not only improved the timeliness, reliability and scalability, but also enhanced the system speed. While, in order to control the low-cost, the Fuzzy-PID compound control algorithm used to control the amount of purifying agent, the algorithm can be adapt to the nonlinear and time-varying and improve accuracy. In this paper, the application of Matlab software to carry on the simulation experiment, proved the feasibility and effectiveness of the algorithm at last.

Abstract: Ship internal equipment vibration will cause the imaging system platform vibration, resulting in blurred images. Wiener Filter is often used to restore the motion blurred image. The principle of the method expects to minimize the mean square error between the restore image and original image. However, this method has some constrains, if parameter selection improper, it generates ringing effect easily. Usually, most users select parameter by rule of thumb, so they frequently fail to generate the optimal solution. In order to get high quality restore image, eliminate the ringing effect, a new approach based on particle swarm optimization (PSO) Wiener Filter was proposed, which automatically adjusts the parameter for Wiener Filter, this method seek the optimal solution by transferring information between individuals and information sharing, which is a highly efficient parallel search algorithm, insuring the accuracy of parameter selection, effectively reducing the ringing effect after image restoration, improve image quality of restoration.

Abstract: Aiming at the phenomenon that the production line of the strip steel’s detection is fast speed and detection quantity of data is large, which are difficult for worker to detect on line, we put forward a detecting system on defect area of the strip steel’s surface. Using CCD camera regularly to collect the images of the strip steel’s surface and to reflect it back to the detecting device on defect of the strip steel’s surface, and adopting specific arithmetic to analyze and handle images, what can accurately sound a warning while it detects the defected image. It is convenient for worker to take corresponding measures right away. This system has simple structure, low cost, and high defect detection rate, which has the great promotional value.
