Abstract: This paper presents the modeling and simulation of the DC Motor closed loop speed control. DC motors have large application area because of their robustness, speed and good load characteristics. Most of the application requires efficient speed control of DC motor. Here performance analysis of speed control of DC motor using PID controller and Fuzzy logic controller is carried out using MATLAB/SIMULINK. Using fuzzy, sensitiveness to variation of input torque and also any kind of system uncertainty can be overcome compared to all other conventional controllers. Finally fuzzy system can provide optimal performance and large range of speed control over the area.
