Abstract :
A model for hysteresis in piezoceramic actuators when they are subject to dynamic voltage excitations is developed. The model uses measurements of the first order reversal curves and the rate of change of the input voltage signal. The model is shown through experiments to offer high accuracy under voltage excitations at frequencies up to 800 Hz
