The so-called Stefan system describes the dynamical model of the liquid–solid phase change in materials ranging from water and ice in the polar caps to metal casting and …
Neurological disorders, such as spinal cord injuries, Parkinson's disease and Alzheimer's disease, limit the functionality of neurons. A recent medical therapy, Chondroitinase ABC …
B Rathnayake, M Diagne - International Journal of Control, 2024 - Taylor & Francis
This paper presents an observer-based event-triggered boundary control strategy for the one-phase Stefan problem, utilising the position and velocity measurements of the moving …
We show the boundary controllability to stationary states of the Stefan problem with two phases and in one dimension in the space variable. In the case of an initial condition that is …
S Koga, M Krstic - IEEE Transactions on Automatic Control, 2023 - ieeexplore.ieee.org
High-relative-degree control barrier functions play a prominent role in automotive safety and in robotics. In this article, we launch a generalization of this concept for PDE control, treating …
We introduce a dynamic event-triggering mechanism for regulating the axonal growth of a neuron. We apply boundary actuation at the soma (the part of a neuron that contains the …
This article proposes a novel control algorithm of a thermal phase-change process and shows its experimental verification using paraffin as a phase-change material (PCM). The …

This contribution presents a backstepping-based state feedback design for the tracking control of a two-phase Stefan problem which is encountered in the Vertical Gradient Freeze …
S Ecklebe, N Gehring - IFAC-PapersOnLine, 2023 - Elsevier
The vertical gradient freeze crystal growth process is the main technique for the production of high quality compound semiconductors that are vital for today's electronic applications. A …
