This paper presented a review study of importance of Proportional Integral Derivative (PID) Controller for speed control of DC motor. Even though the maintenance cost of DC motor is higher than the induction motor, it is widely used in industries as the speed control of DC motor is highly attractive feature for researchers. The PID controller is the very commonly used for control of nonlinear systems. This controller is widely used in many different areas like manufacturing, aerospace, process control, automation etc. The tuning of PID parameter is very tedious. There are various soft [1] computing techniques which are also used for tuning of PID controller to control the speed control of DC motor. Design of PID parameters is important because these parameters have a great impact on the performance of the control system. The affecting parameters in speed control of Dc motor have been discussed.
