“…Besides, an operator-based linear creep model was also reported in [60]. However, these linear creep models have linear and memory free equilibrium values, whist the actual equilibrium value of the creep effect of PEA exhibits hysteresis nonlinearity [89].…”

Piezoelectric actuators (PEAs) have been widely used in micro-and nanopositioning applications due to their fine resolution, fast responses, and large actuating forces. However, the existence of nonlinearities such as hysteresis makes modeling and control of PEAs challenging. This paper reviews the recent achievements in modeling and control of piezoelectric actuators. Specifically, various methods for modeling linear and nonlinear behaviors of PEAs, including vibration dynamics, hysteresis, and creep, are examined; and the issues involved are identified. In the control of PEAs as applied to positioning, a review of various control schemes of both model-based and non-model-based is presented along with their limitations. The challenges associated with the control problem are also discussed. This paper is concluded with the emerging issues identified in modeling and control of PEAs for future research.

“…The frequent shut-on/off of the digital valve often conduces to the hydraulic oil temperature rising fast, which affects the performance of the PZT actuator in reverse [9] . Figure 3 shows the temperature influence on the displacement of the PZT actuator.…”

“…Another model is the Prandtl-Ishlinskii model. [Kuhnen & Janocha, 2001; and [Janocha & Kuhnen, 2000] demonstrated that the classical Prandtl-Ishlinskii operator is less complex and its inverse can be computed analytically. Thus, it is more suitable for real-time applications because minimal mathematical computation time is required.…”
