Safety-constrained position tracking of a flexible transmission system
Anthony Hastir, Timo Reis
We consider safety-constrained position tracking for a flexible transmission system consisting of a torsional shaft driven by a motor and connected to a gravitationally loaded iner…
A Newton--Kleinman Iteration for Infinite-Dimensional Linear-Quadratic Optimal Control
Timo Reis
We develop a Newton--Kleinman iteration for linear-quadratic optimal control of infinite-dimensional systems with possibly unbounded control and observation operators. In this sett…
Prescribed-performance position tracking for infinite-dimensional passive systems
Anthony Hastir, Timo Reis
We study funnel control for linear infinite-dimensional passive systems whose controlled output is obtained by integrating the passive output. In mechanical applications, this corr…
Analysis of a coupled magneto-quasistatic--mechanical model of an eddy current brake
Anna Fischer, Kaja Krhač, Timo Reis +1
We study a coupled magneto-quasistatic model for an eddy current brake. The model leads to a nonlinear infinite-dimensional differential-algebraic system in which the nonlinearity…
Optimal control of infinite-dimensional dissipative systems
Anthony Hastir, Timo Reis
We study the linear-quadratic optimal control problem for infinite-dimensional dissipative systems with possibly indefinite cost functional. Under the assumption that a storage fun…
Abstract second-order boundary control systems
Till Preuster, Timo Reis, Manuel Schaller
Many physical systems, such as vibrating elastic bodies, acoustic media and electromagnetic fields, are governed by second-order evolution equations and inte…
Funnel control for passive infinite-dimensional systems
Thavamani Govindaraj, Anthony Hastir, Lassi Paunonen +1
We consider funnel control for linear infinite-dimensional systems that are impedance passive, meaning that they satisfy an energy balance in which the stored energy equals the squ…
Weak solutions of port-Hamiltonian systems
Timo Reis
We consider port-Hamiltonian systems from a geometric perspective, where the quantities involved such as state, flows, and efforts evolve in (possibly infinite-dimensional) Banach…
The infinite-dimensional dissipation inequality
Timo Reis
We study the dissipativity of linear infinite-dimensional systems with respect to a prescribed quadratic supply rate functional. We characterize this property via an operator inequ…
Regularization and passivity-preserving model reduction of quasilinear magneto-quasistatic coupled problems
Johanna Kerler-Back, Timo Reis, Tatjana Stykel
We consider the quasilinear magneto-quasistatic field equations that arise in the simulation of low-frequency electromagnetic devices coupled to electrical circuits. Spatial discre…
The modulating function method for state estimation and feedback of infinite-dimensional systems
Folke Friedrich, Johann Reger, Timo Reis
We investigate state feedback and observation for infinite-dimensional linear systems, including a variety of partial differential equations with boundary control and observation.…
Linear-quadratic optimal control for infinite-dimensional input-state-output systems
Timo Reis, Manuel Schaller
We examine the minimization of a quadratic cost functional composed of the output and the final state of abstract infinite-dimensional evolution equations in view of existence of s…
