Mechanical system and dynamic control in photolithography for nanoscale fabrication: A critical review

open access: yesInternational Journal of Mechanical System Dynamics, 2021
As one of the most advanced and precise equipment in the world, a photolithography scanner is able to fabricate nanometer‐scale devices on a chip. To realize such a small dimension, the optical system is the fundamental, but the mechanical system often ...

Model-Based Control Design of an EHA Position Control Based on Multicriteria Optimization

open access: yesMachines, 2022
For the control of dynamic systems such as an Electro-Hydraulic Actuator (EHA), there is a need to optimize the control based on simulations, since a prototype or a physical system is usually not available during system design.

Gain-Scheduled Sliding-Mode-Type Iterative Learning Control Design for Mechanical Systems

open access: yesMathematics, 2022
In this paper, a novel gain-scheduled sliding-mode-type (SM-type) iterative learning (IL) control approach is proposed for the high-precision trajectory tracking of mechanical systems subject to model uncertainties and disturbances.

Links of non-free mechanical man-made systems [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение", 2018
The paper gives a complete classification of the links of non-free mechanical technogenic systems. It is shown that the joint use of holonomic and non-holonomic constraints in mechanical systems allows the creation of systems with adaptive properties.

Lagrangian mechanics of active systems [PDF]

open access: yesThe European Physical Journal E, 2021
Abstract We present a multi-scale modeling and simulation framework for low-Reynolds number hydrodynamics of shape-changing immersed objects, e.g., biological microswimmers and active surfaces. The key idea is to consider principal shape changes as generalized coordinates and define conjugate generalized hydrodynamic ...
