Systematic modeling and decoupling control of a pressurized headbox

This paper investigates the modeling and decoupling control of a pressurized headbox in Procter and Gamble Cellulose (now Weyerhaeuser Canada). An systematic modeling method which integrates process mechanism analyses and bump tests is introduced. The coupling degree of the process is analysed and the best variable paring is selected. A feasible decoupling scheme is developed and its implementation on TDC-3000 system is addressed.<
