摘　　要：为实时监测和控制柔性驱动器物理试验装置,利用LabWindows/CVI作为软件平台开发设计了集系统参数配置、控制模式选择、指令控制、实时监控、数据显示和保存于一体的上位机柔性驱动器控制系统软件。采用循环冗余校验算法,设计了与下位机DSP的命令和数据双向传输通信协议以提高系统的可靠性;利用动态数据交换(DDE)技术,实现了采集数据的实时随机存储和指令控制。研究结果表明,数据溢出丢失时,系统利用循环冗余校验算法检测报错,提高了数据和命令双向传输的可靠性;软件系统实现了不同采样频率下的数据动态显示和存储,满足了研究不同控制算法动态性能和系统响应分析的需要,实现了直观有效地监测柔性驱动器工作状态,为柔性驱动器的性能分析和控制算法研究提供了方便、良好的人机交互环境。Aiming at real-time monitoring and controlling of the compliant actuator physical test device, a compliant actuator control system software that integrates system configuration, option of controller model, command control, real-time monitor, data display and saving were proposed and designed based on LabWindows/CVI software platform. By using cyclic redundancy check （CRC）, the bidirectional communication protocol with DSP controller was designed to improve the system reliability. Meanwhile, the random save of the acquisition data and control command were implemented by the Dynamic Data Exchange（DDE）technology. The results indicate that the system error is detected by using CRC if the data overflow,which improves the reliability of data and command communication. The software achieves the data dynamic display and storage under different sampling frequency, meets the analysis need of dynamic performance and system response of different controlling algorithms, and monitors the performance of the compliant actuator intuitively and effectively, which provides convenient and good human-machine interaction environment for the performance analysis and control algorithm research of the compliant actuator.
