ABSTRACT:
Methods, systems, and apparatus, including computer program products, are described for calibrating spindle motor controllers. In one aspect, a method is provided that includes receiving a compensator output from a spindle motor controller that compensates for variations in a velocity of an associated spindle motor, and filtering the compensator output to compensate for a spindle motor system pole and produce a high frequency roll-off.
