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 …

The hysteresis nonlinearities of a magnetostrictive actuator were characterized under
different amplitudes of simple and complex harmonic excitations over a wide range 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 …

The actuating precision of a micro-positioning system, driven by a magnetostrictive actuator,
is adversely limited by its nonlinearities, particularly the output-input hysteresis, which are …

We suggest a new hysteresis model that can describe rate and bias effects of the harmonic
magnetic fields on hysteresis nonlinearities of a magnetostrictive actuator. The proposed …

Magnetostrictive actuators featuring high energy densities, large strokes, and fast responses
are playing an increasingly important role in micro/nano-positioning applications. However …

Smart actuators such as piezoceramics, magnetostrictive and shape memory alloy actuators,
invariably, exhibit hysteresis, which has been associated with oscillations in the open-loop …

Hysteresis of piezoelectric actuators is rate-dependent at high frequencies, but most of the
hysteresis models are rate-independent and cannot describe the rate-dependent hysteresis …

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 material actuators invariably exhibit hysteresis that may be either symmetric or
asymmetric depending upon the actuation principle. Moreover, the shape of hysteresis loop …
