DESIGN OF THE DIRECT CURRENT MOTOR SPEED CONTROLLER WITH EMBEDDED SYSTEM USING FUZZY LOGIC

The development of automatic control processes has played a vital role in the recent engineering applications. Nowadays, traditional control techniques such as proportional integral differential (PID) are very commonly utilized for speed control of electrical motors. However, it is observed that the classical control techniques do not have an adequate performance in the case of nonlinear systems. Because of the simple and continuous control characteristics, the direct current (DC) motors have been widely used in many industrial applications such as robotic manipulators, electric vehicles, steel mills, electric cranes and much more. In this paper, the DC motor speed controller with an embedded system is designed and the speed of DC motor is controlled using a fuzzy logic control (FLC) technique. The controller-based on FLC is investigated with the help of Matlab/Simulink package program. Firstly, the controller is simulated and designed using the Proteus program and then it is implemented with the embedded system using Arduino. The results show that FLC can be successfully used to control the speed of the DC motor with an embedded system
