Odd elasticity in a three-link microswimmer: feedback equivalence, global controllability, and the cost of non-reciprocity
Rossella Attanasi, Gaetano Napoli, Marta Zoppello
We study a Purcell three-link microswimmer whose joints are \emph{odd-elastic}: the torsional stiffness is non-Hermitian, its antisymmetric part injecting mechanical work so…
Purcell swimmer near a wall
Enrico Micalizio, Marco Morandotti, Henry Shum +1
We study the effects of hydrodynamic interactions between a wall and the Purcell three-link swimmer in the two-dimensional case. After deriving the equations of motion in a low Rey…
Controllability and Displacement Analysis of a Three-Link Elastic Microswimmer: A Geometric Control Approach
Rossella Attanasi, Marta Zoppello, Gaetano Napoli
This study investigates the dynamics and controllability of a Purcell three-link microswimmer equipped with passive elastic torsional coils at its joints. By controlling the sponta…
Controllability and kinetic limit of spherical particles immersed in a viscous fluid
Marta Zoppello, Henry Shum, Marco Morandotti
This paper deals with systems of spherical particles immersed in a viscous fluid. Two aspects are studied, namely the controllability of such systems, with particular attention to…
Control of Microparticles Through Hydrodynamic Interactions
Henry Shum, Marta Zoppello, Michael Astwood +1
The controllability of passive microparticles that are advected with the fluid flow generated by an actively controlled one is studied. The particles are assumed to be suspended in…
Gait controllability of length-changing slender microswimmers
Paolo Gidoni, Marco Morandotti, Marta Zoppello
Controllability results of four models of two-link microscale swimmers that are able to change the length of their links are obtained. The problems are formulated in the framework…
Controlling non-controllable scallops
Marta Zoppello, Marco Morandotti, Hermes Bloomfield-Gadêlha
Any swimmer embedded on a inertialess fluid must perform a non-reciprocal motion to swim forward. The archetypal demonstration of this unique motion-constraint was introduced by Pu…
Mean-field and kinetic limit of affine control systems: optimal control through leaders
Marta Zoppello
This paper studies a multi-agent system starting from a single agent dynamics which is a nonlinear affine control system. It analyze what happens when the number of agents goes to…
Hysteresis and controllability of affine driftless systems: some case studie
Fabio Bagagiolo, Marta Zoppello
We investigate the controllability of some kinds of driftless affine systems where hysteresis effects are taken into account, both in the realization of the control and in the stat…
The -link swimmer in three dimensions: controllability and optimality results
Roberto Marchello, Marco Morandotti, Henry Shum +1
The controllability of a fully three-dimensional -link swimmer is studied. After deriving the equations of motion in a low Reynolds number fluid by means of Resistive Force Theo…
A hybrid differential game with switching thermostatic-type dynamics and cost
Fabio Bagagiolo, Rosario Maggistro, Marta Zoppello
In this paper we consider an infinite horizon zero-sum differential game where the dynamics of each player and the running cost are also depending on the evolution of some discrete…
Optimal motion of a scallop: some case studies
Rosario Maggistro, Marta Zoppello
In this paper we focus on a two-link swimmer called scallop which moves changing dynamics between two fluids regimes. We address and solve explicitly two optimal control problems,…
A differential game with exit costs
Fabio Bagagiolo, Rosario Maggistro, Marta Zoppello
We study a differential game where two players separately control their own dynamics, pay a running cost, and moreover pay an exit cost (quitting the game) when they leave a fixed…
Can Magnetic Multilayers Propel Artificial Microswimmers Mimicking Sperm Cells?
Francois Alouges, Antonio DeSimone, Laetitia Giraldi +1
We formulate and solve the equations governing the dynamics of a microscopic artificial swimmer composed of a head and of a tail made of a thin film of permanent magnetic material.…
Purcell magneto-elastic swimmer controlled by an external magnetic field
François Alouges, Antonio Desimone, Laetitia Giraldi +1
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 asymptoti…
Swimming by switching
Fabio Bagagiolo, Rosario Maggistro, Marta Zoppello
In this paper we investigate different strategies to overcome the scallop theorem. We will show how to obtain a net motion exploiting the fluid's type change during a periodic defo…
Swim-like motion of bodies immersed in an ideal fluid
Marta Zoppello, Franco Cardin
The connection between swimming and control theory is attracting increasing attention in the recent literature. Starting from an idea of Alberto Bressan [7] we study the system of…
Optimal Design for Purcell Three-link Swimmer
Laetitia Giraldi, Pierre Martinon, Marta Zoppello
In this paper we address the question of the optimal design for the Purcell 3-link swim-mer. More precisely we investigate the best link length ratio which maximizes its displace-m…
