The method of missing point estimation (MPE) uses the theory of the gappy POD to come up with an efficient method for reduction of nonlinear systems. A general nonlinear CFD model can be written as a linear time-varying (LTV) system. A quantitative criteria based on POD modes is used to select a suitable subset of the original spatial coordinate set. The states of the POD-based reduced-order LTV model can be estimated much more efficiently by conducting projections on these selected states.
