Globally Optimal Robust Control for Large-Scale Sheet and Film Processes
Sheet and film processes such as polymer film extruders, paper machines, and coating processes are large scale and high speed. Addressing model uncertainty for these processes is critically important because model uncertainty can cause the closed loop system to perform poorly. Here an approach is …

Establishment of a repeatable test procedure for measuring adhesion strength of particulates in contact with surfaces
… flavouring particles onto snack surfaces during coating processes is a major concern in the snack production industry. Detachment of flavouring powders from products during handling and production stages can lead to poor appearance and reduced taste of the product as well as substantial financial …
