用于现代运动控制领域的控制器,既需具备强大的计算能力来满足速度和精度的要求,还需具备可重构性能,以便更改或添加新功能.本文提出一种可重构运动控制平台的设计方法,本设计利用可编程片上系统(SOPC)技术,为提高计算能力,用浮点数字信号处理器(DSP)代替片上定点处理器.软件采用基于多线程的框架,比单线程的架构更具柔性.在SOPC Builder工具下对功能模块进行重新组合,可对现场可编程门阵列(FRGA)系统进行快速配置以适应新的功能需求.从算法和功能上来说,该平台具有较好的可重构性,通过对三轴铣床的控制,证明了该设计方法的可行性.

In modern motion control area, controller is required to deliver higher computing capability for adopting advanced algorithms to meet speed and accuracy requirements,and reconfiguration for changing or (and) adding features or functions.This paper presents a methodology in design and implementation of a high performance and reconfigurable platform for motion control.This methodology is in virtue of System on a Programmable Chip (SOPC) technology but replacing the onchip processor by an external high performance,floating-point Digital Signal Processor(DSP).The application of the DSP is designed as a multi-threaded framework,which has more flexibilities than a traditional single-loop one.Furthermore,the Field Programmable Gate Array (FPGA) system can be reconfigured easily and quickly to meet a new requirement by dragging and dropping pre-built components in an SOPC building environment.As a result,the controller platform is more reconfigurable in terms of algorithms and functions.This platform is implemented in a 3-axis milling machine control and the result indicates that the design and implementation presented in thispaper is feasible.
