Integral Action in Output Feedback for Multi-Input Multi-Output Nonlinear Systems
Résumé
We address a particular problem of output regulation for multi-input multi-output nonlinear systems. Specifically, we are interested in making the stability of an equilibrium point and the regulation to zero of an output ro- bust to (small) unmodelled discrepancies between design model and actual system in particular those introducing an offset. We propose a novel procedure which is intended to be relevant to realistic scenarios, as illustrated by a (non academic) example.
