Smart actuators, such as shape memory alloy (SMA) and magnetostrictive actuators, exhibit
saturation nonlinearity and hysteresis that may be symmetric or asymmetric. The Prandtl …

A generalized Prandtl–Ishlinskii model is proposed for characterizing the rate-dependent
hysteresis behavior of smart actuators. A rate-dependent play operator is formulated and …

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

In this paper, a generalized hysteresis model is developed to describe both rate-
independent and rate-dependent hysteresis in piezoelectric actuators. Based on the …

A modified Prandtl–Ishlinskii modeling method for rate-independent hysteresis in
piezoelectric actuators is proposed in this paper. In this method, a generalized backlash …

This paper presents a modified rate-dependent Prandtl–Ishlinskii (MRPI) model for the
description and compensation of the rate-dependent asymmetric hysteresis in piezoelectric …

Magnetostrictive actuators invariably exhibit hysteresis nonlinearities that tend to become
significant under high rates of inputs, and could cause oscillations and error in the micro …

Piezoelectric actuators can offer high resolution of displacement and this makes them
suitable for precise driving tasks. However, most piezoelectric actuators are made of …

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 actuator (PEA) is an ideal microscale and nanoscale actuator because of its
ultra-precision positioning resolution. However, the inherent hysteretic nonlinearity …
