LED Display-Screen is widely used as one of display Terminals to reveal the information in all aspects. With the improvement of living standards, people demand LED display screen to work with the high quality, high speed and high intelligence. The paper presents a method to design LED display-Screen with TMS320F2812 DSP chip of TI, Meanwhile it uses GPRS to communicate with the telephone and the information platform for convenient remote control, it can constitute a large LED display with the CAN bus and so on. The test shows that the system is reasonable, realizable, operated easily, flexible, adaptable to environment, low price, and it is useful in practice after being proved in the practical system.

Full-color LED display-Screen is widely used as a new information display device in all aspects of life, but its flat and static display could not cater to peoples dynamic visual change ,and its lack of intelligence capability makes it a defect not to respond timely with special outside change. ARM and FPGA With high speed and programmable features having been used widely in applications of the embedded development and we provide the method to design of Intelligent Full-Color LED display-screen system based on ARM and FPGA. The control system employs Cortex-M3 core-based ARM as its mail controller, the temperature and humidity sensor, microwave sensor, an infrared sensor are adopted for outside information, and FPGA scan control unit for the color data display. Brushless Direct Current Motor (BLDCM) possessing Superior performance in control unit is widely well applied. The experiments show that the reasonable modular design of the program enables its smooth rotation within the range of 45°-135°, and it timely response to various changes on the outside. Thus LED can display 256 data intelligently which ensures the market prospects. Key words: IntelliSense ; ARM ;FPGA; Full-color LED display-Screen ; Cortex-M3;BLDC motor

Full-Color LED display-Screen is widely used as a new information display device in all aspects of life, the large Full-Color LED Display-Screen color is composed of enhanced MCU or ARM, but the real-time and flexibility of the control system do not satisfy the require of people ,With the continuous improvement of people's living standard. FPGA is favored by the embedded development generally，so a new Full-Color LED Display-Screen was designed based on FPGA and ARM, the system choose the Cortex-M3 ARM as kernel board controller, using the FPGA to scan and control display data, using WI-FI wireless network to communicate though the computer software. The test shows that the system is reasonable, realizable, operated easily, flexible, adaptable environment, low price. This system can support picture to display on 256 gray-scale full-color, and can be communicate with WI-FI on high speed and it will be used widely in the practical system.

This paper analyzes the instantaneous value of the three-phase circuit measurements of various parameters and the key issues to be addressed , to design a new type of intelligent SOPC based on a permanent magnet vacuum circuit breaker control system. FPGA-based NIOS II as the main processor , the more traditional micro-controller with a higher data processing speed and strong expansion capability to effectively meet the electricity system fast data processing capability and high real-time requirements . And with a powerful FPGA logic functions to achieve internal switch control section and the hardware of the control program , than the direct control of the processor using software implemented with higher reliability and noise immunity . The intelligent control system hardware to EP2C35F672C6 core processor,mainly for failure to protect the real-time data acquisition and processing and circuit breakers,real-time display of current or fault line running information, the intelligent controller to achieve two-way communication with the PC function , via the bus system to reach remote remote adjustment, the purpose of the remote control , making the performance of intelligent controller is enhanced to meet the requirements of the distribution system , which provides protection for the safe operation of power system reliability .

A universal fractional-order controller is proposed to asymptotically stable the unstable equilibrium points and the nonequilibrium points of continuous fractional-order chaos systems. The simple fractional-order controller is obtained based on the stability theorem of nonlinear fractional-order systems. The control scheme is simple and theoretically rigorous. The numerical simulations demonstrate the validity and feasibility of the proposed fractional-order controller.
