A Comparison of Iterative Feedback Tuning and Classical PID Tuning Schemes

Abstract: Iterative Feedback Tuning (IFT) is used for tuning PID controllers for the case when it is of interest to reach a new set point level as quickly as possible. A special variant of the IFT criterion is used, where zero weighting is applied during the transient response. The result of the IFT method is compared with the results of three tuning schemes commonly used in industry. It turns out that the IFT method always performs as good as or better than the other methods
