【摘要】 虚拟仪器是计算机技术和传统仪器仪表技术相结合的产物,是仪器发展的一个重要方向。LabVIEW是一个基于图形化编程语言的虚拟仪器软件开发工具。文中基于Lab-VIEW图形化编程语言,针对实际测量中测量系统的工作频带不能满足测量允许误差的问题,采用数字滤波的方法设计了虚拟频率补偿仪,较好地改善了系统的动态特性。该仪器灵活性强,用户可以根据自己的需要任意设置补偿参数,具有硬件方法不可比拟的优越性。更多还原

【Abstract】 Virtual instruments is an important direction of instrument development.The LabVIEW is a kind of software development tool based on graphics language.During actual measurement,since the working frequency of measurement system can not satisfy the tolerance requirement.So this paper analyzes how to develop a frequency compensation apparatus based on LabVIEW graphics language.The apparatus is very flexible,users can set the parameters at will as they need to improve the dynamic performance of the system.更多还原
