High Accuracy Resolver to Digital Converter Based on Modified Angle Tracking Observer Method
A resolver is a rotary transformer where the magnitude of the energy through the resolver windings varies sinusoidally as the shaft rotates. These are unsurpassed in its ability to reliably supply rotary angular position data in the harsh industrial environments. This paper presents the design of so...

Summary: | A resolver is a rotary transformer where the magnitude of the energy through the resolver windings varies sinusoidally as the shaft rotates. These are unsurpassed in its ability to reliably supply rotary angular position data in the harsh industrial environments. This paper presents the design of software based resolver to digital converter based on modified angle tracking observer method to estimated the rotor shaft angle. The proposed resolver to digital converter has been successfully implemented in MATLAB® Simulink and the results are verified by simulation for different rotor speeds. This method brings down the hardware cost and increases the accuracy and reliability. [PUBLICATION ABSTRACT] |
