Tracking servo system using a disturbance observer

摘要

The present design is that, for receiving a gain value and comprises a disturbance value with the gain compensation in the multiplexer the gain compensation in the main surface disturbance observer to output the disturbance observer in a single transmission and the disturbance value with respect to the tracking servo system using the disturbance observer calculating a disturbance value in advance by using the gain value stored in the and to further haejugo offset the combined gain value and the actual disturbance value, a gain value and the calculated disturbance value compensation outputted from the control unit in an adder capable of suppressing the disturbance there is an effect.
