Abstract
In this paper, a new method to collect RRO disturbance data is proposed. The estimated RRO disturbance obtained from the proposed method will not be affected by the variation of the actuator model. Test results show that the servo tracking performance can be significantly improved by using the estimated disturbance to compensate the actual RRO disturbances
