Used of Fuzzy Tool or Pid for Speed Control of Seprately Excited Dc Motor

DC motor has been widely utilized as a part of much mechanical provision for their exact, basic and nonstop control attributes. We have different controller for control dc motor speed with the help of PID& FUZZY TOOLS sliding mode using software Matlab and experiment set up. The International Journal of Electrical, Electronics and Mechanical Controls ISSN (Online) : 2319-7501 Volume 4 Issue 3 September 2015 Manuscript ID : ISSN23197501-V4I3M1-092015 brushless dc motor extensively used for control system and industrial application because small in size, high efficiency and high torque density Design PID controller to get fast step response. The PID controller gives very good response and the controller further tuned to decrease overshoot and steady state error. In industries PID controller are better than other controller. PID controller is not difficult to tune and modest. PID control technique is unable to balance out the nonlinear plants or in the vicinity of limited however high instabilities. This thesis an extensive study to control speed of dc motor by different Controller like PID or FUZZY Sliding mode in Matlab simulation as well as experimental Study on dcmotor. The system identification technique is used to get the accurate transfer function of dc motor system identification is the technique where we give some input to the motor and get output corresponding input and output we get the process model with measured and simulation mode through is model get the best fit percentage result after find the transfer function of plant we have design the different controller to control the speed/position of the motor. We have design PID controller or FUZZY controller for high accuracy speed control.
