Table 73:
Setting the parameters according to Ziegler and Nichols
The adjustment rules of Ziegler and Nichols have been determined for P-controlled systems with a time delay
of the first order and dead time. However, they apply only to controllers with a disturbance reaction and not
to those with a reference reaction.
