【摘要】：转台是一种较简单的机电耦合设施,同时转台也是一种集电子技术和光电设备为一体的综合设施。它在实验室、国防建设、航空工业等众多领域中具有十分重要的意义。转台是半实物的标定、仿真和测试中不能缺少的部件,其质量的好坏与实验的可靠性和可信度有密切的关系,尤其对提升实验室操作能力和科技水平有着无可取代的作用。随着科学技术的快速发展,机械产业越来越精密化,部件的微型化与位移的微量化是以后的主要研究方向,其中准确的位置控制即精密定位技术显得尤为关键。传统的伺服控制设备通常使用微型计算机来完成位置的精准控制,因为其核心电路非常复杂,运算速度非常慢,所以开发功能合适、使用便利、定位精度高的控制平台运动系统具有十分广阔的应用前景。本文提出了一种“PC+运动控制卡”的伺服转台控制系统的设计方案,该系统以控制计算机、运动控制卡、主控机箱、转台设备为平台。主要研究其在转台控制系统中的运用,并给出检验结果。为了完成设计计划,本论文围绕着伺服转台控制系统的工作原理、硬件设计计划、软件设计计划、测试结果这四方面展开。首先,简要说明伺服转台控制系统,并详细分析系统的使用价值和研究背景,阐述国外与国内的研究现状,并具体分析伺服转台控制系统的工作原理,提出系统将要完成的功能设想。其次,根据性能需求选择合适的伺服转台系统,并以伺服转台系统为基础硬件平台,根据要求完成各种控制功能模块。紧接着介绍基于VC++开发平台的软件设计计划,从转台控制软件和数据处理软件两方面来设计,并优化预测跟踪算法,提高转台的控制速度与精度。最终,按照设计计划与实用性能通过实验的方法对伺服转台控制系统进行检验。根据实验结果,表明控制系统达到设计构想,符合设计的具体目标。总结工作内容,就精密伺服转台控制系统的后续发展提出自己的建议。
[Abstract]:Turntable is a simple mechatronic coupling facility. At the same time, turntable is a kind of integrated facility which integrates electronic technology and optoelectronic equipment. It has very important significance in many fields such as laboratory, national defense construction, aviation industry and so on. Turntable is a kind of hardware-in-the-loop calibration, which is indispensable in simulation and testing. Its quality is closely related to the reliability and reliability of the experiment, especially it plays an irreplaceable role in improving the laboratory operation ability and the level of science and technology. With the rapid development of science and technology, the machinery industry is becoming more and more precise. The miniaturization of components and the micro-quantization of displacement are the main research directions in the future. Traditional servo control equipment usually uses microcomputer to complete precise position control, because its core circuit is very complex and the operation speed is very slow, so the development function is suitable and the use is convenient. The motion system of the control platform with high positioning accuracy has a very broad application prospect. This paper presents a design scheme of servo turntable control system of "PC motion control card". The system is based on control computer, motion control card, main control box and turntable equipment. This paper mainly studies its application in turntable control system and gives the test results. In order to complete the design plan, this paper focuses on the working principle, hardware design plan, software design plan and test results of the servo turntable control system. First of all, the servo turntable control system is briefly described, and the use value and research background of the system are analyzed in detail. The present research situation of the servo turntable control system is expounded, and the working principle of the servo turntable control system is analyzed in detail. The functional assumption of the system to be completed is put forward. Secondly, the servo turntable system is selected according to the performance requirement, and based on the servo turntable system, all kinds of control function modules are completed according to the requirements. Then the software design plan based on VC development platform is introduced, which designs the turntable control software and data processing software, and optimizes the predictive tracking algorithm to improve the control speed and precision of the turntable. Finally, the servo turntable control system is tested according to the design plan and practical performance. The experimental results show that the control system achieves the design conception and accords with the design target. This paper summarizes the contents of the work and puts forward some suggestions for the following development of the precision servo turntable control system.
