Abstract
A systematic methodology for designing of linear unknown input observers (UIO) for fault estimation in nonlinear systems is presented. Necessary and sufficient conditions for the existence of linear UIOs for nonlinear systems are derived and as long as these conditions are satisfied, we obtain explicit design formulas for the observer. The method is applied to a non-isothermal chemical reactor (CSTR) subject to a concentration sensor fault.
