Tuning Fractional Order Proportional Integral Controllers Using Dominant Pole Placement Method

This paper presents a method of tuning for fractional order proportional integral controllers for a class offractional order systems. Fractional order proportional integral controller inherits the advantages of the traditionalinteger order PI controller and has one degree of freedom more than the integer order PI controller and it has bettercontrol performance. Based on this characteristic of the FOPI controller, fractional order proportional integral (FOPI)and fractional order [proportional integral] (FO[PI]) controllers proposed and designed based on dominant poleplacement method for the considered class of fractional order systems. The results shows that the proposed methodworks well for the design of fractional order PI controllers.
