Abstract: In this work, the generalized T (GT) distribution is used to develop a statistically robust joint data reconciliation - parameter estimation (DRPE) strategy. The robustness feature is provided by the GT distribution, which includes Normal, Laplacian and Cauchy distribution as special cases. We use historical data to first estimate the parameters of the GT distribution, so that the resulting estimator is efficient when the error is in the GT family. The strategy is implemented in a simulation of a practical chemical engineering plant. The results confirm the robustness and efficiency of the estimator. © 2004 Elsevier B.V. All rights reserved.
