A method and apparatus for generating a comprehensive response model for a sheet forming machine are provided. A finite number of critical points and a response type are used to create a continuous response profile for each actuator zone. The continuous response profile for each actuator zone is discretized into a discrete response profile based on the resolution appropriate for an application. A multi-zone response model for each pair of actuator set and sheet property profile is created from the discretized response profile of the actuator zones in the actuator set. The comprehensive response model for a multivariable sheet-forming machine is created from a collection of multi-zone response models for multiple pairs of actuator sets and sheet property profiles.

Method and apparatus for creating a comprehensive response model for a sheet forming machine

A method and apparatus for creating a generalized response model for a sheet forming machine are provided. Sheet property profiles are measured while the setpoint of an actuator is changed. A response (or change) profile of the sheet property resulting from a setpoint change is calculated. A finite set of critical points are selected from the property response profile. Using the selected critical points, the property response profile is classified in one of a finite number of response types. Under each of the response types, the property response profile is fitted with a plurality of continuous functions associated therewith. These continuous functions are combined to form the response model that minimizes the deviation between the property response and the fitted combination of continuous functions.
