MATHEMATICAL-MODELING AND SIMULATION FOR CARDING

The purpose of this work is to increase the understanding of carding s ystem dynamics based on mathematical tools that will ultimately lead t o the development of on-line real-time controllers for carding. The wo rk comprises both modeling the process and comparing simulated results with experimental data. A mathematical model for one worker-stripper group is described and subsequently expanded to model a carding engine with six carding (worker-stripper) groups. The process variable in th is work is restricted to fiber areal density on the main cylinder; the expanded model predicts output (web) fiber areal density in time. Bot h simulated and experimental results are presented.
