METHOD AND APPARATUS FOR EVALUATING AND SELECTING SIGNAL COMPARISON METRICS
A method for evaluating a simulation model. In the method, for selected test cases, a first performance index is calculated in the simulation model. For the same test case, a second performance index is ascertained in a real test environment. For each of the test cases, a difference is calculated between the first performance index and the second performance index, and a signal metric is determined. For each of the signal metrics, an interrelation between the difference and the respective signal metric is investigated. The signal metric that exhibits the closest interrelation with the difference is selected.

Gray box model estimation for process controller
Parameters are estimated for continuous time linear gray-box models using a fast sensitivity evaluation, which is a measure of how output of the model changes with changes in parameters. A two-step parameter estimation of non-linear models, such as a steady-state model and dynamical model, is performed. A parameter estimation algorithm is employed for estimation of non-linear model parameters via local approximation at different system operating levels or operating set-points. The parameter estimation task is improved by an efficient parameter estimation of linear, continuous-time, stochastic, gray-box models. It is further improved by using a two-step parameter estimation of non-linear, continuous-time, gray-box models. It is still further improved by employing the efficient parameter estimation algorithm for the non-linear gray-box models.
