wide rang of DC motors speed and their easy control are responsible for their widespread operation in industry. Mainly DC motors speed is done by controlling of armature voltage or field control. The introduced speed control methods for DC motors have developed by knowing new methods in control theory. In this research a DC motor speed has been controlled by using Fuzzy control. The effect of load changes, reference speed, and armature voltage have been considered in this controller. The proposed method has been simulated using the information of a DC machine with software MATLAB and the SIMULINK environment.
