数控机床的拥有量和其年产量是一个国家制造能力的重要标志,数控技术的发展促进数控机床的不断发展。当今数控技术的发展趋势是:“PC+运动控制器”的开放式数控系统,运动控制器是处于控制系统软件和硬件之间,它的好坏将直接影响到数控系统的控制精度和速度,所以运动控制器是数控系统的关键部件之一。研制一种可用于实际的运动控制器对于推进国内工业控制的发展和促进运动控制的研究有重要的意义。本文系统、全面地对运动控制器进行了研究,首先分析国内外运动控制器的研究情况和发展现状,进而指出运动控制器的发展趋势。在此基础上对基于PCI 总线的DSP、CPLD 运动控制器进行方案设计,它不是采用传统的专用运动控制芯片进行设计,而是采用DSP、通用PCI 总线接口芯片和CPLD 设计的。并就该运动控制卡硬件设计和软件设计的实现方案进行了深入的讨论,阐述了实现中的技术细节。
The procession and annual output of CNC(Computer NumericalControl) machine indicate the manufacturing ability of the country.Theimprovement of CNC machine benefits from the development of the CNCtechnology.The trend of the numerical control technology is the openarchitecture numerical control system,which based on PC and motioncontroller. Motion controller is placed between the software andhardware and will impinge on the control accuracy and speed of thesystem, so motion controller is one of the most important part of theCNC system. It is important to develop a practical motion controller inaccelerating the domestic industrial control and the study on motioncontrol.In this thesis, montion controller is researched. We analyze theimportance of motion controller in the CNC system and point out thedevelopmental trend of motion controltechnology. A new generationmotion controller is designed.It is a DSP & CPLD motion controllerbased on PCI bus. The design and realization method of hardware andsoftware is discussed. Some technological details during design andrealization are described.
