High Speed Operation Tests of Resolver Using AURIX Microcontroller Interface

Abstract

This paper demonstrates possibility to use microcontroller AURIX TC277 interfaces for resolver signal processing and also for its carrier signal generation. Resolver support is integrated in Delta-Sigma analog to digital converter module. This module also contains resolver carrier signal generation. The paper also describes needed configuration and achieved results for the electrical speeds up to 80 krpm. Measured resolver position is compared with encoder position which is taken as a reference. The results from real experiments on a prepared hardware setup are also contained. The steps needed to achieve good compensation and correspondence between both sensors are detailed.
