【摘要】 20世纪90年代以来,随着集成电路、电力电子技术和交流可变速驱动技术的发展,各国著名电气厂商相继推出各自的交流伺服控制系统系列产品,交流伺服控制系统的设计与开发也在生产实践中发挥着越来越重要的作用。本课题研究的目的是针对机电实验室的滑动轴承实验装置开发数字交流伺服系统,在对轴承实验装置及交流伺服系统原理进行深入分析的基础上,提出了交流伺服控制系统的整体构思方案,选用MINAS A系列交流伺服电机开发伺服控制系统,结合EDA最新研究成果,按照高性能、高精度数字控制系统的发展要求,综合运用单片机、可编程逻辑器件控制技术,尝试性的提出数字型交流伺服系统控制方案并独立完成全部软硬件制作、调试工作。该系统以VB6.0开发驱动控制系统的人机交互环境,以PROTEUS EDA设计软件开发以89S52单片机与XC95108 CPLD可编程逻辑器件为核心的PCB控制电路板,以位置控制方式完成对实验台的速度、位置的微机上位控制,并采用两路AD实时监控实验台的速度转矩信号,完成对轴承模拟信号的采样与传输。交流伺服控制系统设计完成后进行了安装调试,并对测试数据结果进行了分析,经过评测,该控制系统使用方便,成本低廉,完全达到了轴承实验装置对伺服控制系统功能性与经济性的要求。更多还原

【Abstract】 With the development of integrated circuit technology, electrical and electronic technology and adjustable speed AC motors, more and more famous companies have produced own AC servo motors from the 1990s. The design of AC servo system has become more and more important in the practice.This paper introduces a AC servo control system based on a journal bearing test equipment. Author has researched into the bearing test equipment and proposed the overall design plan. The paper choices MINAS A series AC servo motors as drive motor and integrates single chip technology, CPLD technology and new EDA achievements. Author designed the AC servo system and completed the hardware and software independently. The system includes the human-computer interface based on VB6.0 software and the control PCB including 89S52 microchip and 95XC108 CPLD chip based on PROTEUS software. The system controls position and velocity of the bearing test equipment, samples velocity and torque signal and completes the real-time control.After installing , debugging and evaluation of the AC servo control system, the result shows that the system is inexpensive and convenient and fits the requirement of the AC servo control system completely.更多还原
