In most piezoelectric applications, including precision motion control, pressure regulation in micropumps, and force control in microactuators, there is a need to develop a model that accounts for hysteresis and describes both the electrical and mechanical properties of piezoceramics, along with the electromechanical coupling between the two domains. A model that characterizes hysteresis and the coupled electromechanical effect of the sensing and actuating signals is presented. The model presented characterizes the electromechanical properties of a piezoceramic actuator when subject to variable mechanical load disturbance conditions. The model is tested under a range of voltage excitations at frequencies up to and is shown to offer high accuracy.
