A new methodology for gage control of sheet and film processes is presented, A linear process model is developed that is capable of describing many of the interesting features of the process, including a noisy and moving gage sensor, significant process noise, strong coupling between the gage in different lanes, constraints on the actuators, and significant time delay between the actuators and the sensor, An automatic control of this process given this model form is designed, Novel features of the controller are that it can contend with information from a moving sensor and handle hard constraints on the actuators, Control performance and robustness to noise are demonstrated favorably, via simulations.
