Abstract
In this paper, the dynamics, stability, and rational model analysis for designing a whole roller carding system are presented. The plant is a stable but sluggish system of web uniformity. The PID controller is discussed for designing a closed-loop system of roller carding. Since the PI controller is basically a low-pass filter, the compensated system usually has a slower rise time and longer settling time. At first glance, it may seem that PI control improves steady-state error at the expense of stability. Moreover, after the location of the controller's zero is properly selected, both the transient response and steady-state error can be improved. At the same time, good tracking and step disturbance rejection can be achieved by moving all of the poles of the closed-loop system into the left half of the plane during the operation.
