【摘要】 机电一体化技术的发展状况是衡量一个国家机械工业发展水平的重要标志。同工业发达国家相比，我国的机电一体化技术还比较落后。运动控制技术是机电一体化技术的核心部分，提高运动控制技术水平对提高我国的机电一体化技术具有至关重要的意义。因此，对运动控制技术作深入细致的研究，把握国内外运动控制技术的最新发展动态，开发运动控制类产品是摆在我们面前的一个重大课题。 本文对运动控制技术和国内外在这方面的最新成果进行了深入研究，并详细论述了基于专用运动控制芯片的运动控制板卡的开发过程。主要研究内容如下： ①对运动控制系统中的上位控制和伺服驱动等关键技术进行了深入剖析。②详细介绍了直线电机驱动技术，全闭环交流伺服驱动技术，新一代可编程序计算机控制器(PCC)技术等代表运动控制技术发展趋势的几项新技术。③分析了运动控制系统中传动系统和控制系统的设计方法。④分析了计算机控制系统的“三总线结构”，研究了微机控制系统的抗干扰技术，详细介绍了专用运动控制芯片的结构和功能，用ISA总线技术实现了PC机和运动控制芯片之间的数据通讯，设计了运动控制板卡的硬件电路。⑤建立了编制运动控制库函数的基本框架，在此基础上编写了部分运动控制函数。⑥在Windows平台上，用Visual Basic语言编写了运动控制卡的功能测试软件。 本课题开发的运动控制卡一方面可用于构筑具有“NC嵌入PC”式结构体系的开放式数控系统，另一方面，它也为其他机电一体化系统中运动控制的数字化解决方案提供了软、硬件开发平台。更多还原

【Abstract】 The progress of one country? s electromechanical integration technology indicates its mechanical industry level. Compared with the industry developed country, our electromechanical integration technology is under-developed. Motion controlling technology is the core integral part of electromechanical integration technology. It is of great significance for enhancing our electromechanical integration technology to develop motion controlling technology. Consequently, it is an important task to deeply research on motion control technology, to grasp its newest trends and to develop the correlative products.This paper makes deep study on the motion controlling technology and its newest fruit, deep discourse on the process of developing the Motion Controlling Card which is based on the appropriative chip. The main content is as following:(I)Analyzing the pivotal technology of the motion controlling system, such as servo and controlling.(2)Introducing several newest fruit which represents at the trends ofmotion controlling technology expanding, such as the linear motor, the full-closed AC servo and the PCC(Programmable controlling computer).(3)Analyzing the method to design the mechanical transmission and the controlling system of motion controlling.(4)Analyzing the?3-Buses structurd?of the computer controllingsystem; studying on the anti-jamming technology; introducing the structure and function of the appropriative motion controlling chip;realizing the data communication between the PC and the appropriativeIIchip with the ISA?Bus technology; designing the hardware of the Motion Controlling Card.(5)Setting up the primary frame used to design the motion controlling functions, based on which part of such functions are codded.(6)Designing the Motion Controlling Card s function-testing software with Visual Basic Language in Windows.The Motion Controlling Card developed in this thesis is suitable to set up the opening CNC system with the structure of?NC embed in PC?. Also, it provides a hardware and software developing plate, on wkich many motion controlling problems of other electromechanical integration system can be numerically settled.更多还原
