Sampling time dependence of disturbance feedforward compensation performance

Abstract

In this paper, a method for feed-forward cancellation of disturbance effects is proposed, and its positioning performance is evaluated and verified when the acceleration signal is acquired with high sampling. Benchmark Problem proposed by the Investigating R&D Committee on Basis of Collaborative Technologies for Precision Servo Systems is used for the verification. As a result of the verification, it is confirmed that the effect of disturbance can be reduced, and the positioning performance can be improved by using high sampling for the acquisition of acceleration signals.
