作者： Zhengyi Li Xiaoqi Tang Xiangdong Zhou State Engineering Research Center of Numerical Control System School of Mechanical Science and Engineering Huazhong University of Science and Technology Wuhan China

This paper proposes a novel architecture of the numerical control (NC) system based on multiprocessor and real-time Ethernet. To comply with the trend of modular, open framework NC system, the hardware architecture is composed of ARM, DSP and FPGA modules, of which the ARM module is responsible for HMI (human-machine interface), the DSP module is in charge of core calculation, and the FPGA module plays the role of logical operation and constructs a real-time Ethernet for integrating servo drive modules, machine input/output units into the system. The proposed NC system has the advantages of smart reconfiguration, high performance but low cost. Finally, successful utilization of this system for a hoop bending machine control is briefly described.

Transparent conductive oxide thin films are applied to many computer, communication and consumer electronics products including thin film transistor liquid crystal displays, organic light emitting diodes, solar cells, mobile phones, and digital cameras. The laser direct write patterning of the indium tin oxide (ITO) thin film processing technique produces a heat affected zone that has an enormous effect on the electro-optical efficiency of transparent conductive oxide films. This is because direct laser writing patterning in thermal machining process can create debris and micro-cracks in the substrate. Therefore, this study establishes the ultraviolet (UV) laser ablation of temperature model on the polycarbonate and soda-lime glass substrates using the finite element analysis software ANSYS, and measures the temperature field based on the laser micro-patterning process. The meshing model determines the structure of the pre-processors and parameters were set with ANSYS parameter design language. This study also simulates the Gaussian distribution laser irradiation on the pre-processor structure. A UV laser processing system made micro-patterning on ITO thin films to analyze which conditions damaged the substrates. Comparing the simulation and experiment results reveals the minimum laser ablation threshold of the ITO thin films with the melting and vaporization temperatures. Simulation results show that the temperature distribution on PC and soda-lime glass substrates after laser irradiation of 1.05 μs with a laser output power of 0.07 W produces temperatures of approximately 52 °C, 54 °C and 345Cand 205 °C at the laser output power of 0.46 W. The experiment results show that the patterning region is similar to the simulation results, and the lower laser power does not damage the substrates. © 2009.

In this paper, we propose a receding horizon control approach to synchronization for chaotic systems. A new matrix inequality condition on the terminal weighting matrix is proposed for chaotic systems under which nonincreasing monotonicity of the optimal cost is guaranteed. It is shown that the proposed terminal inequality condition guarantees the closed-loop stability of the receding horizon synchronization (RHS) method for chaotic systems. As an application of the proposed method, the RHS problem for Chua's chaotic system is investigated. © 2009 SICE.

It is not easy to processing piston ring contour because of its complicating shape. From view of time-domain analysis, in order to trace the curve of piston ring, servo actuator must have high speed and acceleration to complete movement of back and forth. From view of frequency -domain analysis, the order of harmonic of the piston ring contour is very high, so the control system bandwidth also should be wide enough. It's hard to satisfy these requirements for the traditional drive methods by using rotate serve and Lead screw. In this paper, a new method of direct drive by linear motor is provided, And achieve good results.

7th World Congress on Intelligent control and Automation (WCICA 2008), vol.6

作者： Yucheng Bai Xiaoqi Tang Jihong Chen Fangyu Peng National NC System Engineering Research Center Huazhong University of Science슠and슠Technology Wuhan Hubei China Wuhan Huazhong Numerical Control Company Limited Huazhong University of Science슠and슠Technology Wuhan Hubei China

Two new methods to improve the Ultra-low speed control performance of ac servo system are described in this paper. One is improved M/T method, which could minimize the influence of speed detection dead time and smooth the measurement Another is instantaneous speed detection based on constant jerk model, which assumes the rotor jerk is constant at the interval of sampling period. The instantaneous speed is calculated by analytic geometry. This method can minimize both the speed detection dead time and detection delay, which is the premise of low-speed control. The effectiveness of these methods has been confirmed by experimentation. The experimental system is composed of a digital signal processor (DSP), a field programmable gate array (FPGA), a PWM inverter and a permanent magnet synchronous motor (PMSM).
