This paper deals with the design of Fractional Order Proportional Integral (FO-PIλ) controller for the speed control of DC motor. A mathematical model of DC motor control system is derived and based on this model fractional order PIλcontroller is designed using stability boundary locus method to satisfyrequired 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 PIλ (FO-PIλ ) controller is compared with Integer Order Relay Feedback Proportional Integral (IO-RFPI) controller. Finally the stability of both control system is considered
