Smart actuators employed in micropositioning are known to exhibit strong hysteresis
nonlinearities, which may be asymmetric and could adversely affect the positioning …

Piezomicropositioning actuators, which are widely used in micropositioning applications,
exhibit strong rate-dependent hysteresis nonlinearities that affect the accuracy of these …

Smart actuators such as magneto-restrictive actuators, shape memory alloy (SMA) actuators,
and piezoceramic actuators exhibit different hysteresis loops. In this paper, a generalized …

Hysteresis is an inherent characteristic of piezoelectric materials that can be determined by
not only the historical input but also the input signal frequency. Hysteresis severely …

A formula that characterizes the output of the inverse compensation is derived when the
inverse Prandtl-Ishlinskii hysteresis model is applied as a feedforward compensator. For that …

This study proposes a new rate-dependent feedforward compensator for compensation of
hysteresis nonlinearities in smart materials-based actuators without considering the …

The Prandtl-Ishlinskii (PI) model is widely utilized in hysteresis modeling and compensation
of piezoelectric actuators. For systems with rate-independent hysteresis, the inverse PI …

Apart from the output-input hysteresis loops, the magnetostrictive actuators also exhibit
asymmetry and saturation, particularly under moderate to large magnitude inputs and at …

Piezoelectric, magnetostrictive, and shape memory alloy actuators are gaining importance in
high-frequency precision applications constrained by space. Their intrinsic hysteretic …

This paper presents a novel real-time inverse hysteresis compensation method for
piezoelectric actuators exhibiting asymmetric hysteresis effect. The proposed method …
