摘　　要：A modified Prandtl-Ishlinskii(PI)model with rate-dependent thresholds for describing the hysteresis characteristics of piezoelectric actuators is proposed.Based on the classical PI model,a novel threshold depending on the input rate is constructed.With the novel rate-dependent threshold,the play operator has the capability to track the frequency variation of the input signal.Hence,the proposed modified PI model can be used to depict the rate-dependent hysteresis of piezoelectric actuators.Experimental results are presented to illustrate the model validation results of the proposed modeling.
