APPARATUS AND METHOD FOR IDENTIFYING INFORMATIVE DATA IN A PROCESS CONTROL ENVIRONMENT

摘要

A method for validation of a model in predictive control includes identifying a signal (802) and a disturbance (804) using historical data (122) associated with one or more process variables. The method also includes warelet decomposition (704) of the signal (802) and the disturbance (804) . The method further includes identifying a plurality of points, such as transients or singularities (706) , (1002a-1002b) associated with the decomposed signal (802) using the decomposed signal (802) and the decomposed disturbance (804) . In addition, the method includes selecting at least some of the points (1002a-1002b) and extracting a plurality of data segments from the signal (802) , where the data segments are associated with the selected points (1002a-1002b).
