A Simple Method of Tuning PI Controller for Integrator Dead/Time Processes

Abstract

The paper deals with a new simple and effective proportional-integral controllers tuning method for an integrating plus dead-time transfer function model. The method is based on a pole placement technique. The selection of dominant poles is given in the function of the dead-time model. Proportional and integral controller gain is received in a simple way by applying the given equation. The comparison with other methods for the set-point and disturbance response, as well as the robustness onto the effect of the unknown changes, shows the efficiency of the proposed method.
