High-Performance Speed Measurement by Suppression of Systematic Resolver and Encoder Errors

A. Bunte, S. Beineke

Abstract

The subject of this paper is a method which suppresses systematic errors of resolvers and optical encoders with sinusoidal line signals. The proposed method does not require any additional hardware and the computational efforts are minimal. Since this method does not cause any time delay, the dynamic of the speed control is not affected. By means of this new scheme, dynamic and smooth running characteristics of drive systems are improved considerably.
