    Global output regulation for output feedback systems with an uncertain exosystem and its application

    INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL, Issue 15 2010
    Dabo Xu
    Abstract This paper presents the solvability conditions for the global robust output regulation problem for a class of output feedback systems with an uncertain exosystem by using output feedback control. An adaptive control technique is used to handle the unknown parameter vector in the exosystem. It is shown that this unknown parameter vector can be exactly estimated asymptotically if a controller containing a minimal internal model is employed. The effectiveness of our approach has been illustrated by an asymptotic tracking problem of a generalized fourth-order Lorenz system. Copyright © 2009 John Wiley & Sons, Ltd. [source]

    A feedforward,feedback controller for infinite-dimensional systems and regulation of bounded uniformly continuous signals

    Abstract We design a controller for infinite-dimensional linear systems (with bounded control, observation and feedthrough operators) which, under certain assumptions, achieves asymptotic tracking of arbitrary bounded uniformly continuous reference signals in the presence of disturbances. The proposed controller is of feedforward,feedback type: The dynamic feedback part is used to stabilize the closed-loop system consisting of the plant and the controller, whereas the feedforward part is tuned using the regulator equations to achieve the regulation of desired signals. We also completely solve the regulator equations for SISO systems, and we discuss robustness properties of the proposed controller. A useful feature in our design is that the feedforward part of the controller can be designed independently of the feedback part. This automatically leads to a degree of robustness in the stabilizing part of the controller, which is not present in the existing state feedback controllers solving the same output regulation problem.

    Robust output regulation for discrete-time nonlinear systems

    INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL, Issue 2 2005
    Weiyao Lan
    Abstract In this paper, we will establish a framework that can convert the robust output regulation problem for discrete-time nonlinear systems into a robust stabilization problem for an appropriately augmented system consisting of the given plant and a specific dynamic system called internal model. We then apply this framework to solve the local robust output regulation problem for a general class of discrete-time nonlinear systems. The results of this paper gives a discrete-time counterpart of the recent results on the continuous-time robust output regulation problem. Copyright © 2005 John Wiley & Sons, Ltd. [source]

    On a robust synchronization problem via internal model approach,

    ASIAN JOURNAL OF CONTROL, Issue 1 2010
    Weijie Sun
    Abstract This paper formulates the synchronization of the Duffing system and the Van der Pol oscillator as a robust output regulation problem and presents the solution to this problem based on the internal model design. The controller thus obtained is able to achieve the synchronization of the outputs of these two systems in the presence of the parameter uncertainty of the Duffing system.

    Output regulation of discrete-time linear plants subject to state and input constraints

    INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL, Issue 8 2003
    Guoyong Shi
    Abstract Discrete-time output regulation of linear systems with state and/or input constraints on magnitude is considered. Structural properties of linear plants are identified under which the so-called constrained semi-global and global output regulation problems are solvable. As in the case of continuous-time systems, an important aspect of our development is a taxonomy of constraints showing a clear relationship between the constraint types and the output regulation results. Solvability conditions are developed for semi-global and global output regulation problems. Appropriate regulators are constructed for problems that are solvable.
