“…[11] However UKF has been barely applied to solve chemical engineering problems especially for nonlinear distributed parameter systems. [12] One of the successful applications has been the state estimation of a lumped parameter CSTR system by Romanenko and Castro. [13] Another one is for the stratified domestic hot water storage tank described by nonlinear PDEs.…”

“…Then, traditional state estimation and/or control methods from finite-dimensional system theory can be exploited for the resulting early lumped systems. The widely-utilized early lumping methods are reported as: modal analysis (Galerkin's method) [47,48], finite difference [49], proper orthogonal decomposition (POD) [50,51], finite element method (FEM) [52], FEM Galerkin cubic b-splines method [53], etc. In contrast, late lumping means that one conducts observer, filter, and/or controller design steps on the original infinite-dimensional space and applies spatial approximation later for simulation purposes, where the backstepping method [54,55], the adjoint-based approach [56], and the Crank-Nicolson method [57] are widely used.…”

“…In Alonso et al the most appropriate sensor type and locations are chosen through a guided search algorithm that minimizes orthonormality distortion, using a low dimensional representation of the original distributed system. As the system observability also depends on the inputs, Kreuzinger et al indicate that simulation is the best way to investigate the system dynamics to deduce reasonable sensor locations and appropriate simplifications. They implemented their results together with an unscented Kalman filter or a Luenberger structure observer to monitor a stratified storage tank.…”
