Title: METHOD AND APPARATUS FOR DESIGNING MODEL-BASED CONTROL HAVING TEMPORALLY ROBUST STABILITY AND PERFORMANCE FOR MULTIPLE-ARRAY CROSS-DIRECTION (CD) WEB MANUFACTURING OR PROCESSING SYSTEMS OR OTHER SYSTEMS
Abstract:
A method includes obtaining (902) a model (304) associated with a model-based controller (104, 306) in an industrial process (100, 302) having multiple actuator arrays (114, 116, 118, 120) and performing (914) temporal tuning of the controller. The temporal tuning includes adjusting one or more parameters of a multivariable filter (308) used to smooth reference trajectories of actuator profiles of the actuator arrays. The temporal tuning could also include obtaining (904) one or more uncertainty specifications for one or more temporal parameters of the model, obtaining (916) one or more overshoot limits for the actuator profiles, identifying (918) a minimum bound for profile trajectory tuning parameters, and identifying (920) one or more of the profile trajectory tuning parameters that minimize one or more measurement settling times without exceeding the one or more overshoot limits. The controller could be configured to use the adjusted parameter(s) during control of the industrial process such that the adjusting of the parameter(s) alters operation of the controller and the industrial process.
