A novel two stages funnel controller limiting the error derivative Journal Article

has been accepted for publication in SCL. The key novel contribution is the consideration of an intermediate control signal, which first specifies what the ideal value for the error derivative is and then the controller is designed in such a way that the error derivative is close to this desired signal (in addition to ensuring that the error stays in the funnel all the time).

Switched nonlinear DAE paper accepted

Our paper

Chen, Yahao; Trenn, Stephan

On impulse-free solutions and stability of switched nonlinear differential-algebraic equations Journal Article

Abstract | Links | BibTeX

has been accepted for publication in Automatica. A key result is, that the method I and Daniel Liberzon presented in 2012 is probably not the correct approach to study impulse-freeness and stability for nonlinear switched DAEs, because this 2012-method (centered around assumption A4) is not invariant under nonlinear coordinate transformation.
