WebbBecause a narrower proportional band gives greater output change for any given deviation, it therefore also makes the control performance more susceptible to oscillation. At the same time, a narrower proportional band reduces the offset. Reducing the proportional band to its smallest limit (proportional band = 0%) results in ON/OFF … Webb29.1 Proportional Control Mode. In the proportional ... mode is that the one-to-one correspondence of proportional mode is available and integral mode eliminates the inherent offset. 29.7 Proportional-Derivative Control Mode.
