摘要：
A systematic method for the design of linear unknown input observers (UIO) for sensor fault estimation in nonlinear systems is developed. Necessary and sufficient conditions for the existence of linear UIOs for nonlinear systems are derived. 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. & COPY; 2023 Elsevier Ltd. All rights reserved.
