Performance assessment and retuning of PID controllers for load disturbance rejection

Abstract In this paper we propose an algorithm for the load disturbance rejection performance assessment of a PI(D) controller and for the retuning of the parameters in case the obtained response is not satisfactory. The technique can be applied simply by evaluating the load disturbance closed-loop response. The automatic tuning for a set-point filter is also proposed in order to address the set-point following task. Simulation results show the effectiveness of the methodology.
