Design And Implementation Of Fast Parameter Tester For Resolver

Resolver is mainly used for measuring axis rotation speed and angle position,compared with similar sensors，it has high resolution,low cost and environment toadapt to a wide range of advantages,etc. it can be used for the aviation, spaceflight,ballistic missiles,artillery,hybrid and electric vehicles purposes. The demand forresolver is very large,for the detection of resolver, the traditional method is to be fixedin machanical dividing apparatus, through the manual rotating find voltage zero, andthen according to certain angle stepping successive comparison test. Since this methodtime-consuming, operation-complex, unable to adapt to the demand of production linetesting, it becomes a bottleneck for the industrialization of resolver. This paperinvolves the fast parameter tester for resolver based on tracking type resolverdecoder,and USB6009,and LabVIEW fixed-point calibration, which can completeresolver driving and angle fast testing, effectively solve the existing problems, andmake the industrialization of resolver be possible.According to the background, purpose and significance of the research topic, thepaper introduces the domestic and foreign development situation of angularmeasurement technique and angular error calibration technology for resolver, putforward to an fast parameter testing scheme for resolver which construct by trackingtype resolver decoder,and USB6009,and fixed-point calibration with LabVIEWthrough comparing and analysising all methods. The system uses a test form ofcalibration angle, which can be rapidly measured to obtain the voltage zero point, polenumber, angle value of resolver and the error of the calibrated angle.Error of the system are analyzed in detail, various factors which can cause themeasurement error are pointed out,idiographic expressions and mathematicalrelationships for these errors are deduced. In this way, a reliable basis was provided forreducing the measurement and improving the accuracy of angular measurement; andsome ways which can restrain or compensate the errors are introduced. Finally, thedebugging for hardware and software is finished, the experiment result shows that thesystem can reliably be operated and have high real-time performance.
