Abstract

Iterative Control is used to obtain high tracking performance on vibration testing equipments. It is important to find proper frequency response function for Iterative Control because it has information of real system. Signal processing to make proper frequency response function for Iterative Control has been investigated. Electro-hydraulic actuated system was considered as theoretical model. Main performance parameters were found by considering the convergence of Iterative Control Algorithm. Signal processing to make proper frequency response function for Iterative Control was suggested on the basis of previous described works. The usefulness of suggested signal processing method was verified by testing the Iterative Control algorithm on 1 axle vibration testing equipment.
