Precise actuation is a widely utilized technology in the realm of high-end equipment.
Piezoelectric actuators (PEAs) stand out due to their exceptional attributes, including high …

This article proposes a new discrete-time predictive sliding mode control (DPSMC) for a
parallel micropositioning piezostage to improve the motion accuracy in the presence of …

Metaverses have caused significant changes in the industry and their academic foundation
can be traced back to the term cyber–physical–social systems (CPSS), which was proposed …

In order to overcome the typical cross-scale motion contradiction between the large motion
range (radian scale) and high displacement resolution (microradian scale) in single …

Precise trajectory tracking of piezo actuators (PEAs) in real time is essential to high-
precision systems and applications. However, the real-time tracking accuracy is rather …

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 …

In laser systems, beam pointing usually drifts as a consequence of various disturbances, eg,
inherent drift, airflow, transmission medium variation, mechanical vibration, and elastic …

The new axially pre-compressed macro-fiber composite bimorph (MFC-PBP) can produce
large displacement and output power. However, it has the property of strong rate-dependent …

This paper proposes an efficient strategy to simultaneously insert multiple objects, which are
parallel connected by passive compliant mechanisms, in precision assembly. The …

A laser projection positioning technique for large composite production based on a scanning
galvanometer is proposed in this paper. First, based on the projecting model of the scanning …
