CLOSED-LOOP ALIGNMENT IDENTIFICATION WITH ADAPTIVE PROBING SIGNAL DESIGN TECHNIQUE FOR WEB MANUFACTURING PROCESSING SYSTEMS

摘要

A method includes designing (308, 400, 500) probing signals for testing an alignment of actuators (202) in a web manufacturing or processing system (100) with measurements of a web (108) of material being manufactured or processed by the system. The method also includes providing (310) the probing signals during alignment testing to identify the alignment of the actuators with the measurements of the web. Designing the probing signals includes designing the probing signals based on both spatial and dynamic characteristics of the web manufacturing or processing system.
