 		 #4393 - RE: control the DC motor's speed with PWM ?
Hello:
I have finished the circuit with MOSFET Driver to dirve the motor and IR sensor to detect the speed of the motor. What the problem is, I have no correct MCS51 routine for Controlling the speed. Now I have a rountine,it is not fine. I calculates the duty of PWM with the formula "D=Dold*Tactual/Tdesired",but the motor rotate is not stable.How should I do?

Best!
