SPEED CONTROL OF DC MOTOR USING FUZZY LOGIC THESIS

Fuzzy Logic Controllers were proposed to achieve the speed control of a DC motor using combined armature voltage and field current by varying the armature voltage in the constant torque region and the field current in the constant power region. Author links open overlay panel A. It is a robust, easily controllable strategy. A direct current DC motor is supposed to be operated at an accurate and constant speed even if the load on the system is increased or decreased. For more information, visit the cookies page. Abstract A direct current DC motor is supposed to be operated at an accurate and constant speed even if the load on the system is increased or decreased. DC Motors are widely used in industries for various purposes.
