Abstract: This paper analyzed vehicle rollover dynamic model when vehicle steering and rollover is occurring, which based on basic vehicle rollover problems. Three-degree-of-freedom vehicle roll model which considering roll angle was established, and physical quantities of model were analyzed. Input and output quantities were analyzed based on vehicle roll model, feedback quantities were determined, too. Controller state reset was added into traditional controller switch module so as to avoid undesired instantaneous pulse which appeared during switching. Three-degree-of-freedom vehicle roll model was put up in Simulink, Controller parameters set was tuned and I/O data were prepared to optimize control effect. The control method in this paper was verified finally.

Abstract: In order to make a research on the vehicle`s ABS and AFS system,the fuzzy neural network controller was designed on the basis of the electric vehicle`s steering and braking models. Then the genetic algorithms was used to improve the parameters of the membership function. Finally, the Matlab/Simulink simulation software has been used in the simulation analysis. The result of simulation proves that the designed system has good tracking performance and more stronger systemic robustness .

Abstract: With the expansion and accelerated pace of development of the steel industry, unattended becomes an inevitably trend. The measuring data of the enterprise becomes crucial importance. Therefore, this paper proposes a system solution to establish comprehensive backtracking model and structure design of concentrated distributed measurement control. Firstly, introduce the process of measuring control model; secondly, establish the measurement control backtracking model and its sub module based on the control process; finally, it is the structural implementation and verification of backtracking model. The Kunming Iron&Steel distribution measurement control system was transformed according to the scheme, and good performances have been achieved in practical application.

Abstract: With the rapid development of world economy, the quality control of products becomes the core and key of competitivenessin the enterprise. The requirements of the complex quality control model are more urgent. Therefore, based on the background of the quality control of steelmaking and rolling material in metallurgy process industry, this paper presents a comprehensive backtracking model of quality control based on the hierarchical. Firstly, analyze the steelmaking and rolling process, then analyze and partition hierarchical operation structure. Secondly, introduce the comprehensive backtracking model, to establishbacktracking model ofthe quality control process. Finally, associatively combine the quality grading hierarchical system structure scheme with backtracking model of the quality control process, and apply it to the actual quality control. Its operation result shows that the classification control and coordination function of the model is good.

Abstract: This paper established a mathematical model of the Pneumatic manipulator speed servo system, and its simulation is passed by Simulink. Through the analysis of systems performance,the PID correction methods of the system is improved. The stability of the system is increased greatly after the PID correction. In the end, the improved method is pointed out.

Abstract: Sliding model control is adopted to pneumatic position servo system by taking full use of its non-sensitivity merit towards the model error and the parameter changing as well as exterior disturbance, and then the sliding model controller is designed, Some uncertainty of model was added to the system simulated .The simulation result indicates that the proposed control plan is effective, and the system also has good robustness.

Abstract: For the smart home with energy management which belongs to the demand-side of power grid, this paper designed a kind of home appliance control module based on the wireless network communication system. Common home appliance can be inserted into smart home system through this module and can be used immediately, which greatly increases the scalability of the system. After commissioning, we make it to control appliances effectively and monitor energy consumption in real time, which proves its validity, rationality and stability. Users can operate and monitor home appliances remotely through indoor smart terminals, Internet and mobile phones.

Abstract: In this paper, a remote control platform for the smart homes using mobile phones has been designed and implemented by based on the latest Web technologies. The functions of monitoring and management for smart homes are integrated in this mobile-based platform. In order to achieve the flexible control of mobile terminals, an friendly interface has been designed, which is able to fit with different sizes of smart phones. Smart phones can communicate with the Web servers through internet and connect to smart home control systems. The results indicate that users are able to access the electrical appliances, check the environment and security status at home anytime and anywhere. The mobile-based remote control platform for the smart home system can give users great flexibilities convenience, with the requirement of demand-side energy management.
