    Controlling DC motor speed in four quadrant operation without microcontroller

    actually its a challenge from my friend.They want me to do such things.Initally i thought to use a dc generator with the shaft of the motor and calibrate the output voltage with speed.output of this generator is converted to digital and comapre with desired speed.but don't how to implement it.So...
