I would like to know how many different ways we can control a motor.
The first i found is through PWM and this can be easily implemented using either opamps or timer ciruits. if i am right for this circuit only open loop control can be achieved. If feedback is to be implemented without using a sensor (tachometer) how can it be done.
Another way i found is through PIC control in which feedback control can be easily implemented.
Is there any other ways in which we can control the speed of a motor ? If i was to make a project on small dc motor speed control , can anyone suggest me a title as i am preparing myself for a degree project?
