See full text

A method and system for controlling a scanning system for a paper machine is disclosed. The scanning system includes a first scanner having a first sensor head and a second scanner having a second sensor head and positioned downstream of the first scanner. Proportional integral derivative control maintains the first and second scanners on their corresponding trajectory arrays. The second scanner tracks the same location of the sheet as the first scanner and the first trajectory array is recalculated at each execution cycle.
