GRAY BOX MODEL ESTIMATION FOR PROCESS CONTROLLER

摘要

A method includes using first principles and engineering knowledge to define a continuous time nonlinear gray-box model of a system performing a process, defining a numerically tractable optimization problem for parameter estimation of the nonlinear gray-box model, tuning a vector of parameters of a static model of the nonlinear gray-box model, and extending the vector of parameters of the static model to a dynamic model by fitting measured transient data from the process.
