Abstract :
This paper presents an advanced spindle servo system with a disturbance observer for an optical disc drive. The system reduces steady state deviation to 0.2% or less with wide range of rotational speed and 50% variation of torque coefficient. Stable control by transient state was confirmed by changing low pass filter function.
