This paper considers output regulation for a 1-d wave equation with disturbances generated from an unknown finite-dimensional exosystem. By decoupling the original system into a PDE-ODE cascade system through solving a Sylvester equation, an adaptive observer is utilized to estimate all possible unknown frequencies that affect a transformed system with disturbance only in the tracking error. Based on the estimates of the unknown frequencies, a tracking error based feedback control is designed to achieve output regulation for this PDE, using only the tracking error and achieving asymptotic convergence.
This paper considers output regulation for a 1-d wave equation where the disturbances generated from an unknown finite-dimensional exosystem. By solving a Sylvester equation, the original system is decoupled into a PDE-ODE cascade system. An adaptive observer is adopted to estimate all possible unknown frequencies that have entered into a transformed system which has disturbance in tracking error only. By the estimates of the unknown frequencies, we are able to design a tracking error based feedback control to achieve output regulation for this PDEs where the tracking error is solely used and the asymptotic convergence is achieved.
