Abstract
The general problem of controlling both machine and cross‐directional properties on sheet and film forming processes is treated. A flexible class of linear dynamic‐stochastic models capable of characterizing the process and disturbance dynamics in these systems is suggested. Procedures are presented for identifying these models from data collected from common scanning type sensors. Linear‐Quadratic‐Gaussian (LQG) control theory is used to design multivariable controllers capable of jointly controlling the machine and cross‐directional property variations using both lumped and spatially distributed actuators.Keywords
