Abstract

The Integral Resonant Control (IRC) is a simple low-order control scheme that has been introduced as a high-performance controller design methodology for flexible structures with collocated actuator-sensor pairs. It is capable of achieving significant damping, over several modes, while guaranteeing closed-loop stability of the system in presence of unmodelled out-of-bandwidth dynamics. These reasons make the IRC an ideal controller for various industrial damping applications, if packaged in a simple easy-to-implement electronic module. In this work, we propose an analog implementation of the IRC scheme using a single Op-Amp circuit. The goal is to demonstrate that with a simple analog realization of the modified IRC scheme, it is possible to damp a large number of vibration modes. A brief discussion about the modeling, circuit considerations, implementation and experimental results is presented in order to validate the usefulness and practicality of the proposed analog IRC implementation.
