Identification of Frequency Response Function of Shaking Table with a New Estimator
Shaking table is a nonlinear system,which is a more nonlinear system with payload.System can be usually as linear system nearby working point in control strategy.H1-estimator or H2-estimator is used for identifying the Frequency Response Function (FRF) of the system.H1-estimator is a lower-estimator and H2-estimator is an over-estimator,both have large estimating errors.In this paper,a new estimator,Hm-estimator,is used for the identification of the shaking table systems FRF,and whose parameters are estimated by differential evolution (DE) which makes Hm closed to the true FRF H.This control strategy can reduce the steps of iterative learning control (ILC)of shaking table system,and the affection of payload characteristic.
