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…
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.…
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
We consider abstract second order systems of the form , which are typically analyzed via the operator matrix $\mathcal{A}=\left[\begin{smallma…
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…
