基于虚拟仪器的开关磁阻电机监控系统

Monitoring system of switched reluctance motor based on virtual instruments

为了提高开关磁阻电机控制系统的实用性和可靠性,利用NI虚拟仪器构建了监控系统,可以实时监测和调整电机运行时的重要参数。该方案以装有数据采集卡的PC机和DSP作为硬件基础,利用LabVIEW软件将各类传感器传送的信号进行实时处理,同时记录和显示各项数据,然后再利用相应的算法完成对数据的分析。DSP则作为PC机故障时的备用系统。实验证明,该控制系统的实用性和可靠性比之前大大提高。

In order to improve the practicability and reliability of the control system of switched reluctance motor （SRM）, a monitoring system was made based on the NI virtual instrument. This system can be applied to the real-time monitoring and ad- justment of the important parameters of running motors. The scheme takes a computer with data acquisition card and a DSP as basic hardwares of this system, and utilizes powerful software LabVIEW to process the signals transmitted by all kinds of sen- sors in time, as well as record and display each data simultaneously. A corresponding algorithm is used to analyze those data. DSP is the standby equipment when the PC goes wrong. Experiments show the practicability and reliability of the control system has been greatly enhanced.
