Nonlinear controlled port-Hamiltonian systems: Existence of (optimal) solutions
Willem Esterhuizen, Bernhard Maschke, Till Preuster +2
We investigate the existence of solutions of reversible and irreversible port-Hamilto\-nian systems. To this end, we utilize the associated exergy, a function that is composed of t…
MPC without Terminal Ingredients Tailored to the SEIR Compartmental Epidemic Model
Willem Esterhuizen, Philipp Sauerteig, Stefan Streif +1
We consider the SEIR compartmental epidemic model subject to state and input constraints (a cap on the proportion of infectious individuals and limits on the allowed social distanc…
Globally convergent homotopies for discrete-time optimal control
Willem Esterhuizen, Kathrin Flaßkamp, Matthias Hoffmann +1
Homotopy methods are attractive due to their capability of solving difficult optimisation and optimal control problems. The underlying idea is to construct a homotopy, which may be…
Path Planning for Concentric Tube Robots: a Toolchain with Application to Stereotactic Neurosurgery
Matthias K. Hoffmann, Willem Esterhuizen, Karl Worthmann +1
We present a toolchain for solving path planning problems for concentric tube robots through obstacle fields. First, ellipsoidal sets representing the target area and obstacles are…
Critical Clearing Time Estimates of Power Grid Faults via a Set-Based Method
Willem Esterhuizen, Gyula Molnár, Tim Aschenbruck +3
This paper is concerned with estimating critical clearing times in the transient stability problem of power grids without extensive time-domain simulations. We consider a highdimen…
Model Predictive Control Tailored to Epidemic Models
Philipp Sauerteig, Willem Esterhuizen, Mitsuru Wilson +3
We propose a model predictive control (MPC) approach for minimising the social distancing and quarantine measures during a pandemic while maintaining a hard infection cap. To this…
