Advanced application of statistical and fuzzy control to textile processes

A new control strategy is proposed to optimize the slasher control parameters and the slashing operation during normal, transient and creep speed. An expert system detects and identifies off-limit or failure conditions and generates command signals for low-level control of slasher components such as creel, size box drying section, and beamer drive. It also addresses the issues of system integration between warping and weaving at a hierarchical level. Simple process models for each section of a slasher are simulated on computers. Simulated results from these models demonstrate that the control strategy is efficient and robust.
