Abstract :
The aim of this paper is to the design and study of a robustness feedback for an intelligent measurement system and more specifically for the main constituent of its digital part-the analog-to-digit converter. The robustness feedback is based on a simplified reference model of the converter. It is introduced by simple means in order to reduce the quantization error. The main contributions are: design of a new type of structure of analog-to-digit converter; development of a model of the robust converter; quantization error reduction by multiple measurements. The behavior of the proposed converter is studied in environment SIMULINK of the MATLAB program package
