The function of speed control in DC motors is very essential in the achievement of desirable outputs. DC motors are designed for use in industrial and commercial applications such as the pump and blowers, material handling, system and gear drives, and adjustable speed drives. Both the nonlinear and linear of DC motor mathematical model is derived and the system model also represented in the form of continuous state space equation. Four type of controllers namely Proportional-Integral-Derivative (PID) controller, state-feedback controller, fuzzy logic controller and fuzzy PID controller are considered for controlling the speed of dc motor by giving the step input signal. The system is simulated using MATLAB/SIMULINK software. The system responses under the four different controllers are also analysed and discussed in term of their performances.
