In this paper we present an automatic tuning methodology for PID controllers for distributed-lag processes. The technique is based on the evaluation of a closed-loop set-point or load disturbance step response and it can be therefore employed with process routine operating data. Further, a performance assessment index is also proposed in order to establish when the performance of a PID controller can be improved by retuning it according to the proposed method. Simulation results show the effectiveness of the approach.

Abstract

In this paper we present an automatic tuning methodology for PID controllers for distributed-lag processes. The technique is based on the evaluation of a closed-loop set-point or load disturbance step response and it can be therefore employed with process routine operating data. Further, a performance assessment index is also proposed in order to establish when the performance of a PID controller can be improved by retuning it according to the proposed method. Simulation results show the effectiveness of the approach.
