example in sinusoidal patterns often referred to as u201c picket fence u201d patterns prior to the invention of the present application correction of mapping misalignment has required manual adjustment of the control settings that can consume an extended period of production and may require disabling the cd control system during the correction one aspect of the present invention overcomes this problem by recognizing mapping misalignment determining improved cd control settings and applying the improved cd control settings to fine tune a cd controller and thereby improve upon or correct the misalignment so that the cd controller will have improved and consistent long term performance the cd control of the present application is preferably included within a controller 134 for the paper making machine 108 although it can be included within a separate controller not shown coupled to the controller 134 the following questions are addressed herein what regions of the cd profile exhibit mapping misalignment how should the impact on the paper making machine 108 be measured as a result of new control settings and how should the cd control settings be adjusted to correct the mapping misalignment and achieve improved performance in answer the present invention introduces an automated optimization technique that determines the locations of mapping misalignment establishes an effective performance indicator to measure the impact of mapping misalignment and applies a searching technique embodied in.
