Cross-direction profile control systems on paper machine.

Multiple Property Cross Direction Control of Paper Machines

Cross direction (CD) control in sheet-forming process forms a challenging problem with high dimensions. Accounting the interactions between different properties and actuators, the dimensionality increases further and also computational issues arise. We present a multiple property controller feasible to be used especially with imaging measurements that provide high sampling frequency and therefo...

Paper Machine -deposit Control Tools & Mechanisms

M any of the paper machine runnability problems that are difficult to detect, monitor, and control are caused by hydrophobic particles. These can be, for example, binder-rich particles in coated broke, wood pitch or stickies associated with recycled fiber. The most important characteristic indicating propensity for runnability problems has proven to be the size, or the increase in size, of hydr...

Autonomic Machine Control - A Case Study (Short Paper)

This paper describes an autonomic machine control system applied to the adaptive control of a modular soldering machine. The particular case concerns the creation of a novel modular production machine with an integrated distributed agent control system, which will be sold worldwide from mid 2008. The agent model is described in terms of the specific customer requirements and specific advantages...

Parallel Alternating-Direction Access Machine

This paper presents a theoretical study of a model of parallel computations called Parallel Alternating-Direction Access Machine (padam). padam is an abstraction of the multiprocessor computers adena /adenart and a prototype architecture usc/omp. The main feature of padam is the organization of access to the global memory: (1) the memory modules are arranged as a 2-dimensional array, (2) each p...
