1. An atherectomy system comprising:
a controller configured to configured to control rotation of a rotational device, the controller comprises:
a speed feedback module configured to receive a position indicator signal indicating a position of a drive mechanism; and
a speed compensation module, the speed compensation module including a damping control module; and
wherein the speed compensation module is configured to receive a speed of the drive mechanism from the speed feedback module and the damping control module is configured to determine a control signal based on the speed of the drive mechanism and output the control signal to control the drive mechanism.
