Numerical estimation of the lock-in domain of a DC/AC inverter
Anton Ponomarev, Lutz Gröll, Veit Hagenmeyer
We estimate the lock-in domain of the origin of a current control system which is used in common DC/AC inverter designs. The system is a cascade connection of a 4-dimensional linea…
Stability of two-dimensional SISO LTI system with bounded feedback gain that has bounded derivative
Anton Ponomarev, Lutz Gröll
We consider a two-dimensional SISO LTI system closed by uncertain linear feedback. The feedback gain is time-varying, bounded, and has a bounded derivative (both bounds are known).…
What ODE-Approximation Schemes of Time-Delay Systems Reveal about Lyapunov-Krasovskii Functionals
Tessina H. Scholl, Veit Hagenmeyer, Lutz Gröll
The article proposes an approach to complete-type and related Lyapunov-Krasovskii functionals that neither requires knowledge of the delay-Lyapunov matrix function nor does it invo…
Time Delay in the Swing Equation: A Variety of Bifurcations
Tessina H. Scholl, Lutz Gröll, Veit Hagenmeyer
The present paper addresses the swing equation with additional delayed damping as an example for pendulum-like systems. In this context, it is proved that recurring sub- and superc…
Characteristics-based Simulink implementation of first-order quasilinear partial differential equations
Anton Ponomarev, Julian Hofmann, Lutz Gröll
The paper deals with solving first-order quasilinear partial differential equations in an online simulation environment, such as Simulink, utilizing the well-known and well-recomme…
On Norm-Based Estimations for Domains of Attraction in Nonlinear Time-Delay Systems
Tessina H. Scholl, Veit Hagenmeyer, Lutz Gröll
For nonlinear time-delay systems, domains of attraction are rarely studied despite their importance for technological applications. The present paper provides methodological hints…
