In order to enhance openness and flexibility of industrial robot control system, an open control system based on double-CPU was designed. An embedded industrial computer based on 86 CPU with Windows XP worked as the upper-system, which implemented HMI and management of the open control system. A FPGA(Field Programmable Gate Array) and another same embedded industrial computer with RT-Linux worked as the lower-system, which implemented realtime motion control of the open control system. Ethernet based on a user-defined Ethernet type was used for exchanging data between the two CPU. Experimental results of the open control system being used for controlling a 5 DOF(Degrees of Freedom) flexible-joint manipulator demonstrate that performance of the system can satisfy requirements of different industrial robot application. © 2011 IEEE.

Adaptive generalized predictive decoupling control for a class of MIMO nonlinear systems based on unmodeled dynamic compensation

For a class of uncertain multi-input-multi-output (MIMO) discrete-time nonlinear systems with strong coupling and unstable zero-dynamics, an adaptive generalized predictive decoupling switching control method based on unmodeled dynamic compensation is proposed. It is only required that the higher order nonlinear terms of the system to satisfy a linear growth condition, rather than the global boundedness condition widely used. The analysis of stability and convergence of the adaptive control method are performed. Moreover, in designing the nonlinear generalized predictive decoupling controller, we combine the adaptive-network-based fuzzy inference system (ANFIS) training with the "one-toone mapping" technique to adaptively estimate the unmodeled dynamics, so that the universal approximation property of ANFIS can be guaranteed. Finally, simulation results demonstrate the superiority of the proposed method and validate the theoretical analysis.

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. ©2009 IEEE.

A New Method for Piston Ring Contour Cutting Based on Linear Driving

引用

13th International Conference on Advanced Design and Manufacture

作者： Zhang, Yicheng Chen, Zhihua Yang, Liangcai Chen, Jihong Tang, Xiaoqi College of Mechatronic Engineering and Automation National University of Defence Technology China State Engineering Research Centre of Numerical Control System Huazhong University of Science and Technology China Reserch Institute of Numerical Control Kunming University China

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.

Journal of Chongqing University 2008年第2期7卷 145-150页

作者：许万 The State Engineering Research Center of Numerical Control System Huazhong University of Science and Technology

We presented a clock synchronization method that contained a clock adjusting algorithm and a frequency compensated clock to achieve precise synchronization among distributed clocks based on IEEE 1588 ***,we presented its application on Ethernet and implementation of the frequency compensated clock in a field programmable gate array(FPGA) as *** results indicate that this method can support sub-microsecond synchronization with inexpensive standard crystal oscillators.
