Ziegler Nichols Tuning Calculator: How it works
| Description How it works |
The Ziegler Nichols tuning calculator works by using Named Formulae to calculate the ultimate gain and the critical frequency as described under this application of the Bode plot. The formulae used are similar those in the Bode plot tool. There are additional formulae for calculating the ultimate Gain (Ku) and period of oscillations (Pu). The tuning values are calculated from the following formulae:  |
