Cross Direction Control that Uses Optimizing Control Method and Fuzzy Logic, 2000 Process Control, Electrical & Info. Conference Proceedings

Takashi Sasaki--In this paper, we introduce Yokogawa’s concept of cross direction control. There are two main concepts in our cross direction control. The first concept is called as Virtual Actuator Corresponding Optimizing Control that aims to minimize the estimate function made from interaction matrix. And this concept is applied mainly to the process that has adequate linearity as in the case of basis weight profile control by dilution water. The second concept is Expert Fuzzy Control that is made into control algorithm from manual operation method of expert operators. This concept is applied mainly to the process that has strong non-linearity as in the case of basis weight profile control by slice lip. This expert fuzzy control can also be applied to coat weight profile control by blade and basis weight profile control in biaxially oriented machines of plastic film.
