The hysteresis of the piezoelectric actuator exhibits obvious rate dependence, especially in
fast scanning or tracking. This article proposes an adaptive hysteresis compensation method …

Hysteretic nonlinearity behavior ubiquitously occurs in mechanical systems, particularly in
high-precision instruments, which severely degrades system output performance …

This article presents an event-triggered adaptive NN command-filtered control for a class of
multi-input and multi-output (MIMO) nonlinear systems with unknown rate-dependent …

Hysteresis behaviors exist in piezoelectric ceramics actuators (PCAs), which degrade the
positioning accuracy badly. The classical Bouc–Wen (CB–W) model is mainly used for …

Macro fiber composite (MFC) is widely used in active vibration and deformation control. The
intrinsic asymmetric hysteresis nonlinearity of MFC affects the control accuracy. In this paper …

Electromagnetic components greatly contribute to the peculiar timbre of analog audio gear.
Indeed, distortion effects due to the nonlinear behavior of magnetic materials are known to …

This paper presents an adaptive hysteresis compensation approach for a piezoelectric
actuator (PEA) using single-neuron adaptive control. For a given desired trajectory, the …

Fast steering mirrors (FSMs), driven by piezoelectric ceramics, are usually used as actuators
for high-precision beam control. A FSM generally contains four ceramics that are distributed …
