Using the intelligent controller to control DC motors speed: An application in the industrial field

This study is to design and use an intelligent controller for stable speed control of a DC motor and compare this intelligent controller with the conventional PID controller. Based on Nichol's PID controller design approach, this study performs model analysis and calculates the parameters Kp, Ki, Kd. Then, the study proposes a solution to combine the PID controller with the fuzzy controller to form an intelligent controller. The study process is implemented by Matlab simulation method. The study’s results show that the intelligent controller ar better than the conventional PID controller in controlling speed of a DC motor. Especially, the starting current of DC motor when using the intelligent controller is only 1/6 of that of PID controller.
