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-freedomby the multiple dominant pole method for integrating plants with a time delay on the basis of D-transform. The approach is fullyanalytical and it enables so tuning that the servo and regulatory responses are non-oscillatory without overshoots. The uses areshown in the example.
