But not correctly, the motor is powered from the 5V supply which is only good for low speed/load. Also, this trick will not work when powering from 12V. Report comment ...

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.

This paper presents a comparative study of Z-N method and Genetic Algorithm method (GA) to determine the optimal Proportional-Integral-Derivative (PID) controller parameters, for speed control of ...
