Controllability and Optimal Control of Microswimmers: Theory and Applications

C Moreau - Journal of the Physical Society of Japan, 2023 - journals.jps.jp
The process of swimming at the microscopic scale is successfully described as a finite-
dimensional, nonholonomic control system due to negligible inertia in the low-Reynolds …

Local controllability of the two-link magneto-elastic micro-swimmer

L Giraldi, JB Pomet - IEEE Transactions on Automatic Control, 2016 - ieeexplore.ieee.org
A recent promising technique for robotic micro-swimmers is to endow them with a
magnetization and apply an external magnetic field to provoke their deformation. In this …

Optimal strokes for driftless swimmers: A general geometric approach

T Chambrion, L Giraldi, A Munnier - ESAIM: Control, Optimisation …, 2019 - esaim-cocv.org
Swimming consists by definition in propelling through a fluid by means of bodily movements.
Thus, from a mathematical point of view, swimming turns into a control problem for which the …

Purcell magneto-elastic swimmer controlled by an external magnetic field

F Alouges, A Desimone, L Giraldi, M Zoppello - IFAC-PapersOnLine, 2017 - Elsevier
This paper focuses on the mechanism of propulsion of a Purcell swimmer whose segments
are magnetized and react to an external magnetic field applied into the fluid. By an …

The control of particles in the Stokes limit

BJ Walker, K Ishimoto, EA Gaffney… - Journal of Fluid …, 2022 - cambridge.org
There are numerous ways to control objects in the Stokes regime, with microscale examples
ranging from the use of optical tweezers to the application of external magnetic fields. In …

Swimming at low Reynolds number

L Berti, L Giraldi, C Prud'Homme - ESAIM: Proceedings and …, 2020 - esaim-proc.org
We address the swimming problem at low Reynolds number. This regime, which is typically
used for micro-swimmers, is described by Stokes equations. We couple a PDE solver of …

Modeling and steering magneto-elastic micro-swimmers inspired by the motility of sperm cells

M Zoppello, A De Simone, F Alouges… - Atti della Accademia …, 2018 - cab.unime.it
Controlling artificial devices that mimic the motion of real microorganisms, is attracting
increasing interest, both from the mathematical point of view and applications. A model for a …

Numerical methods and optimization for micro-swimming

L Berti - 2021 - theses.hal.science
This thesis is devoted to modelling and simulating swimmers at low Reynolds number. Two
computational frameworks are devised for these purposes, and they are used in synergy …

An optimal control approach to ciliary locomotion

J San Martin, T Takahashi, M Tucsnak - Mathematical Control and …, 2016 - hal.science
We consider a class of low Reynolds number swimmers, of prolate spheroidal shape, which
can be seen as simplified models of ciliated microorganisms. Within this model, the form of …

Controllability of low Reynolds numbers swimmers of ciliate type

J Lohéac, T Takahashi - ESAIM: Control, Optimisation and Calculus …, 2020 - esaim-cocv.org
We study the locomotion of a ciliated microorganism in a viscous incompressible fluid. We
use the Blake ciliated model: the swimmer is a rigid body with tangential displacements at its …
