基于LabVIEW的开关磁阻电机瞬态转矩测试系统研究

根据开关磁阻电机的特性和瞬态转矩的计算原理,对开关磁阻电机的瞬态转矩测量进行了研究;并利用虚拟仪器技术和PCI-6250多功能数据采集卡开发了一个开关磁阻电机瞬态转矩测试系统.该系统根据数据采集及其相关的计算原理,结合LabVIEW以及数据配置程序MAX,通过PCI板卡对开关磁阻电机进行数据采集,可对电机的转矩、转速、相电压和相电流等瞬态特性进行瞬时测量,并可在终端客户机上进行同步波形及数值的显示,同时可由用户对实时测量的数据进行保存.

Research on transient torque measuring system of switched reluctance motor based on LabVIEW

There are many factors which are correlatively used in technical capability evaluation, and the indexes are not independent, so the traditional linear evaluation methods are not suitable for technical capability evaluation. For this purpose, the methods of fuzzy measurement and integrals are introduced. Using software outsourcing enterprise as an example, an evaluation index system of technological capability of software outsourcing enterprise is proposed. The index system covers five major aspects: technical environment, technical resources, technical innovation, technical learning and technical management. Then, the fuzzy integral method is used to assess technical capability and the empirical analyses on samples of investigated data from three software outsourcing enterprises are conducted to testify the scientificity and operability of evaluation system.
