Abstract
The first order process model altogether with the proportional-integral (PI) controllers represent the most popular setting for controller design applied in practice. The paper compares the performance of two disturbance observer based PI controllers, one designed using a FOPDT model combined with a loop linearization based on inverse input-output steady-state characteristic and the second using an IPDT model identified in several working points by a relay experiment. Both approaches are compared by means of a nonlinear laboratory plant model.
