Nonlinear state estimation of a power plant superheater by using the extended Kalman filter for differential algebraic equation systems

•Developed first-principles dynamic model of an industrial superheater/reheater.•Developed and applied a nonlinear estimator algorithm for DAE system.•Compared model and estimator results with dynamic data from an operating plant.•Estimator yielded considerably superior results for all variable that...
