Abstract

Hysteresis is a form of nonlinearity that is present in piezoceramic microactuator systems. A methodology to predict influence of hysteresis on system performance is valuable when these actuators are employed as part of closed loop motion control systems. In this work, an existing phenomenological approach (Preisach models) is investigated for piezoceramic systems. Hysteresis in a piezoceramic system is experimentally documented initially for a bounding operating condition of a cyclic electric potential. The limiting hysteresis loop has a positive turning point of +100 V and a negative turning point of -100 V. Hysteretic behavior for various operating conditions within this bounding loop (i.e. minor hysteresis loops) is then predicted using a moving Preisach model. In addition, hysteresis effects are analytically predicted when a constant mechanical load and a cyclic electric potential are applied simultaneously, using two inputs Preisach model. Experimental data are also presented for the minor hysteresis loops at different positive and negative turning points. Predictions using Preisach models agreed well with the experimental results, particularly when the minor loops are closer to the bounding loop.
