This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

A novel approach has been investigated for the application of engine idle speed control. The control method implemented, "Fuzzy Control", has the advantage of not requiring the knowledge of a ...

He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.
