In this approach, a performance index is employed with specification of the infinity-norm of the sensitivity and complementary sensitivity functions. This criterion determines desire values of PI controller parameters for a bank of FOPDT models. Then an Evolutionary polynomial regression is applied to extract a tuning rule for PI controllers. At the end, the performance of recommended method is evaluated by several case study simulations. ER -
