This paper deals with the design of Fractional Order Proportional Integral (FO - PI?) controller for th e speed control of DC motor. A mathematical model of DC motor control system is derived and based on this model fractional order PI? controller is designed using stability boundary locus method to satisfy required gain margin (GM) and phase margin (PM) of the system. Servo and Regulatory tracking simulation runs are carried out for the speed control of DC motor . The performance of the fractional order PI? (FO - PI? ) controller is compared with Integer Order Relay Feedback Proportional Integral ( IO - RF PI) contr oller. Finally the stability of both control system is considered.
