Unified approach to analog and digital two-degree-of-freedom PI controller tuning for integrating plants with time delay

Abstract

The article describes the unified approach to the tuning of the analog and digital PI controller with two-degree-of-freedom by the multiple dominant pole method for integrating plants with a time delay on the basis of D-transform. The approach is fully analytical and it enables so tuning that the servo and regulatory responses are non-oscillatory without overshoots. The uses are shown in the example.
