Nonlinear Internal Models for Output Regulation

Internal Models for Nonlinear Output Agreement and Optimal Flow Control

This paper studies the problem of output agreement in networks of nonlinear dynamical systems under time-varying disturbances. Necessary and sufficient conditions for output agreement are derived for the class of incrementally passive systems. Following this, it is shown that the optimal distribution problem in dynamic inventory systems with time-varying supply and demand can be cast as a speci...

In this paper we show how nonlinear internal models can be effectively used in the design of output regulators for nonlinear systems. This result provides a significant enhancement of the non-equilibrium theory for output regulation, which we have presented in the recent paper " Limit Sets, Zero Dynamics, and Internal Models in the Problem of Nonlinear Output Regulation " .

Nonlinear Output Regulation by Post-Processing Internal Model for Multi-Input Multi-Output Systems

The paper deals with the problem of output regulation for the class of multiinput multi-output square nonlinear systems satisfying a minimum-phase assumption and a “positivity” condition on the high-frequency gain matrix. By following a design paradigm proposed in [12] for single-input single-output nonlinear systems, it is shown how an internal model-based controller can be obtained, whose dim...

Nonlinear Output Regulation

A classical problem in control theory is to impose, via feedback, a prescribed steady-state response to every external command in a given family. This may include, for instance, the problem of having the output of a controlled plant asymptotically track any prescribed reference signal in a certain class of functions of time, as well as the problem of having this output asymptotically reject any...
