The purpose of this work is to increase the understanding of carding system dynamics based on mathematical tools that will ultimately lead to the development of on-line real-time controllers for carding. The work 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 this work is restricted to fiber areal density on the main cylinder; the expanded model predicts output (web) fiber areal density in time. Both simulated and experimental results are presented.
Rust et al. (1994) studied this question.
