Unknown Input Observer Design for a Class of Semilinear Hyperbolic Systems With Dynamic Boundary Conditions

The problem of unknown input observer design is considered for coupled PDE/ODE systems subject to incremental sector bounded nonlinearities and boundary inputs. Assuming available measurements at the distributed domain, synthesis based on Lyapunov methods recast in terms some matrix inequalities. Numerical simulations support confirm theoretical findings, illustrating robust estimation performances proposed nonlinear observer.
