چکیده
This paper propose an optimal tuning method for fractional PI controller. The method consist of minimizing Integral Time Absolute Error (ITAE) performance index criterion. The fractional PI controller are achieved by diffusive representation and the optimum setting of fractional controller parameters are reached by using conventional optimization algorithm. An example of application is presented to evaluate the proposed method. A comparison with classical PI controller shows that the system is robust to gain variations.
