摘要
针对正交3-PRRRR移动并联机构特点,采用"PC+运动控制卡"的方案设计了正交3-PRRRR移动并联机构的控制系统。系统主要由硬件和软件两部分组成。以NI公司的LabVIEW8.5作为开发平台,通过PCI-7340四轴运动控制卡和UMI-7764多功能数据采集卡实现对机构3个自由度的驱动控制。实验结果表明控制系统能够准确地实现单轴和多轴的联动控制,包括对动平台的位置、速度和加速度等运动参数的设置。该系统软件操作方便、界面友好。
Aiming at the orthogonal 3-PRRRR tanslational parallel manipulator,a PC motion controller-based control system of an orthogonal 3-PRRRR tanslational parallel manipulator was presented.The system was mainly composed of hardware and software.Using NI＇s LabVIEW8.5 as a development platform,the three translations of the 3-PRRRR parallel mechanism were controlled through the PCI-7340 four-axis motion controller and UMI-7764 multifunction data acquisition card.The results indicate that the control system can achieve accurate single-axis and multi-axis controls,including motion parameters of the moving platform position,velocity and acceleration,and the system has a friendly interface and is easy to use.
