Table 9 Tension results of fluctuation phase under periodic variations of yarn target tension.
From: Research on yarn tension control technology for knitting underwear machine based on adaptive ADRC
Tension fluctuation phase | Target tension increases by 20cN | Target tension reduces by 20cN | ||
|---|---|---|---|---|
Overshoot/cN | Response time/s | Undershoot/cN | Response time/s | |
PID | 12.60 | 0.94 | 7.74 | 0.69 |
ADRC | 9.98 | 0.62 | 5.79 | 0.48 |
Adaptive ADRC | 7.20 | 0.47 | 4.13 | 0.24 |
