Design of the Double-channel Angle Measurement System Based on Data Fusion
Angle measurement is the key technology of digital control and angular position tracking in servo system.For the problem of low accuracy of angle measurement and error in coarse-fine data coupling,data fusion was applied in the doublechannel angle measurement system.The angle was simultaneously measured by coarse channel and fine channel,then the coarse data and fine data was coupled by data fusion algorithm which has the function of error carry correction and zero correction.Finally,the upper-computer software was designed based on LabVIEW to processing data and display angle.The text results showed the system can effectively improve the accuracy of angle measurement.
