【摘要】 制造业的发展水平是一个国家综合实力的象征,在制造业中应用广泛的运动控制技术是推动制造业变革的重要力量,开发出稳定、高效、可靠的运动控制系统是其中的关键。PC机的快速发展把运动控制系统的研究吸引到基于PC机的路线上,根据目前标准化开放式体系结构的概念,就结构形式而言,基于PC机的开放式数控系统包括三种类型：“PC嵌入NC”结构的开放式数控系统、“NC嵌入PC”结构的开放式数控系统和“SOFT”型数控系统,其中后两种类型是现在发展的主要趋势。本文在系统、全面地对这两种类型控制系统的体系结构和系统平台进行研究的基础上,以精密X-Y平台为控制对象,针对这两种类型,设计出能完成运动控制基本功能的数控系统,包括基于GT-400-SV运动控制卡设计的开放式数控系统和基于PCL-726和PCL-8331／0板卡设计的分布式数控系统,并且对这两种数控系统的性能进行比较,可以总结出两者各有优缺点,前者实时性好,开发周期短,但是开放性不够；后者可以提供最大的灵活性,最高的性能价格比,但是开发过程相对复杂。运动控制实验在数控系统开发和控制算法的研究中具有举足轻重的作用,MATLAB语言是科学研究领域应用最广的语言之一。本文中把Quanser公司开发的基于MATLAB语言的实时控制卡Q8引入运动控制实验中来,并且提出一种验证运动控制效果的新方法,即用墨盒喷墨实现运动轨迹的实时绘制。通过实验证明了提出方案的可行性,Q8卡和墨盒在运动控制实验中的应用,对于运动控制研究具有重要的意义。更多还原

【Abstract】 The level of manufacturing is the symbol of national power. One of the important factors that impel the manufacturing is motion control technology. The motion control system which has high stability, efficiency and credibility is the key. Go with the great progress of PC technology, the motion control system based PC gains the chance to develop. According to the current standard of open architecture CNC system, the open CNC based PC includes three types. That is "PC Embed NC", "NC Embed PC" and "SOFT based CNC". The last two of the three types are the main current at present.Follow the systemic and comprehensive research of the last two types of motion control system, the corresponding system is designed in the paper. For example, use the GT-400-SV motion controller to design "NC embed PC" system, use PCL-726 and PCL-833 to design "SOFT based CNC" system which look the X-Y table as the control object. Through the compare with the two kinds of system, gained some count conclusions. All of them have virtues and flaws. Example, the first has good real time performance and short exploitation period, but it is not a complete opening control system. The second one offers biggest agility and highest ratio of capability to price, but its exploitation process is complex.Motion control experiment is important in the CNC system’s exploitation and control arithmetic’s research. MATLAB is one of the widest languages used in science study. The QUANSER produced a kind of real-time control card based on MATLAB, which is named Q8. In this paper, the card is used in motion control experiment. At the same time, HP inkjet box is used in the experiment too. The experimental result shows that Q8 and HP inkjet box have important signification on the motion control.更多还原
