Hysteresis hinders the effective use of piezoelectric smart materials in sensors and actuators. This paper proposes a hybrid model that can precisely portray hysteresis in piezoelectric actuators, which is constructed by a preisach operator with a piecewise uniform density function. Then, the corresponding inverse model for hysteresis is developed. It studies online recursive identification of hysteresis drift. Based on the obtained models, a method for simultaneous compensation of the hysteresis of piezoelectric actuator is applied to the control of system nonlinearities. Simulation and experimental results based on an IPMC actuator are provided to illustrate the proposed approach. The result verified the validity of the model and effectiveness of the controller.

Magnetostrictive actuators play an important role in the perception of usefulness of smart materials and devices. Their applications are potentially wider than that of piezoelectric actuators because of the higher energy density and intrinsic robustness. However, the non-negligible hysteresis and complexity of their characteristics make the design and control quite difficult and has limited their diffusion in industrial applications. Nevertheless, the scientific literature presents a wide offer of results in design and geometries, modeling and control that may be exploited for applications. This paper gives a reasoned review of the main results achieved in the literature about design, modeling and control of magnetostrictive actuators exploiting the direct effects of magnetostriction (Joule and Wiedemann). Some perspectives and challenges about magnetostrictive actuators development are also gathered.
