The onset of self-organized motion is studied in a poroelastic two-phase model with free boundaries for Physarum microplasmodia (MP). In the model, an active gel phase is assumed to be interpenetrated by a passive fluid phase on small length scales.

In two-dimensional reaction-diffusion systems, local curvature perturbations on traveling waves are typically damped out and vanish. However, if the inhibitor diffuses much faster than the activator, transversal instabilities can arise, leading from

Mathematical modelling of natural phenomena
Traveling localized spots represent an important class of self-organized two-dimensional patterns in reaction-diffusion systems. We study open-loop control intended to guide a stable spot along a desired trajectory with desired velocity. Simultaneous

By establishing an alternative foundation of control theory, this thesis represents a significant advance in the theory of control systems, of interest to a broad range of scientists and engineers. While common control strategies for dynamical system

Self-propelled motion, emerging spontaneously or in response to external cues, is a hallmark of living organisms. Systems of self-propelled synthetic particles are also relevant for multiple applications, from targeted drug delivery to the design of

Optimal Trajectory Tracking of Nonlinear Dynamical Systems ISBN: 9783319465739
This chapter drops the assumption of exactly realizable trajectories and allows for arbitrary desired trajectories \(\varvec{x}_{d}\left( t\right) \). The regularization parameter of optimal control is assumed to be small and used for a perturbation

This chapter introduces the notion of exactly realizable trajectories. The necessary formalism is established, and after the definition of exactly realizable trajectories, the linearizing assumption is introduced. This assumption defines a class of n

Reaction-diffusion systems model phenomena from a large variety of fields. The analytical approach pursued in this thesis can be used to obtain solutions to optimal control for a number of systems with relative ease. The formalism based on projectors

This work deals with the position control of selected patterns in reaction-diffusion systems. Exemplarily, the Schlogl and FitzHugh-Nagumo model are discussed using three different approaches. First, an analytical solution is proposed. Second, the st
