Abstract: This paper deals with output regulation with non-linear exosystems. The dynamic system itself is assumed to be linear. Non-linear observer design techniques are exploited for the internal model design. A new strategy for internal model design is proposed, based on a dynamic extension of the existing non-linear observer design for the non-linear exosystem. Additional filters are used to estimate the invariant manifold in the state space subject to the non-linear exosystem. The proposed design for the internal model and control ensures that the state variable asymptotically converge to the invariant manifold, which implies that the regulated output state asymptotically converge to zero.
Keywords: output regulation; linear systems; nonlinear exosystems; observer design; internal model design; nonlinear observers; nonlinear control.
