Unknown Input Observer Design for Linear Time-Invariant Systems -- A Unifying Framework
Markus Tranninger, Helmut Niederwieser, Richard Seeber +1
This paper presents a new observer design approach for linear time invariant multivariable systems subject to unknown inputs. The design is based on a transformation to the so-call…
Integral state-feedback control of linear time-varying systems: A performance preserving approach
Richard Seeber, Markus Tranninger
An integral extension of state-feedback controllers for linear time-varying plants is proposed, which preserves performance of the nominal controller in the unperturbed case. Simil…
Higher-order sliding mode observer design for linear time-invariant multivariable systems based on a new observer normal form
Helmut Niederwieser, Markus Tranninger, Richard Seeber +1
In various applications in the field of control engineering the estimation of the state variables of dynamic systems in the presence of unknown inputs plays an important role. Exis…
Detectability Conditions and State Estimation for Linear Time-Varying and Nonlinear Systems
Markus Tranninger, Richard Seeber, Martin Steinberger +2
This work proposes a detectability condition for linear time-varying systems based on the exponential dichotomy spectrum. The condition guarantees the existence of an observer, who…
Strong Detectability and Observers for Linear Time Varying Systems
Markus Tranninger, Richard Seeber, Juan G. Rueda-Escobedo +1
This work presents a notion of strong detectability for linear time varying systems affected by unknown inputs. It is shown that this notion is equivalent to detectability of an au…
Uniform Detectability of Linear Time Varying Systems with Exponential Dichotomy
Markus Tranninger, Richard Seeber, Martin Steinberger +1
Exponential dichotomies play a central role in stability theory for dynamical systems. They allow to split the state space into two subspaces, where all trajectories in one subspac…
