Identification and Control of a Cryogenic Current Comparator Using Robust Control Theory

Abstract

This paper presents the model identification of a cryogenic current comparator (CCC). A dynamic model set is obtained and compared with the experimental data in order to provide a realistic dynamical behavior of the system. To improve the performance of the CCC, an H-infinity optimal controller is designed based on this model set. In this framework, a robust stability guarantee is provided and the simulations of the closed-loop system illustrate the performance and robustness improvements.Fil: Bierzychudek, Marcos Eduardo.
