IMC based PID controllers are being used to speed control of DC motor and DC servomotor in industry. Asthis controller offer good performance comparitive to conventional controllers like PI, PID and Ziegler Nicholsfrequency method controllers. This paper presents the speed control of the DC motor and DC servomotorusing PI, PID, Ziegler Nichols method and IMC-PID controllers, to realize the optimization of control action. Amathematical calculation of DC motor and DC servomotor has developed and simulations are carried out inMATLAB/ Simulink environment.From the results, it is observed that time domain parameters like rise time 0.6 secs, settling time 2 secs,speed for peak over shoot 1450, peak amplitude 1, with no oscillations using IMC-PID controller on DC motor.And for DC servomotor its rise time is 0.3 seconds, settling time is 1 second, speed for peak overshoot 1450rpm, peak amplitude 1 with absence of oscillations by using IMC-PID controller
