Resilient control systems should efficiently restore control into physical systems not only after the sabotage of themselves, but also after breaking physical systems. To enhance resilience of control systems, and given an originally minimalinput controlled linear-time invariant(LTI) physical system, we address the problem of efficient control recovery into it after removing a known system vert...

This paper shows a strategy to carry out a wind turbine LPV (Linear Parameter Varying) and MIMO (Multivariable Input and Multivariable Output) model from a family of LTI (Linear Time Invariant) models. The family of LTI models is obtained from a linearization process in different operational points of the wind turbine model in GH Bladed. The procedure is valid for any family of LTI models obtai...

We consider the design of three different control architectures for a step response tracking problem within a class of linear time-invariant (LTI) plants. Our goal is to motivate the use of a particular switching architecture that has been the subject of our prior work. We present the design of the particular switching architecture that we use and characterize its step response performance (mea...

The natural cytotoxicity receptor NKp46 (encoded by Ncr1) is an activating receptor expressed by innate lymphoid cells (ILC), including NK cells, a subset of γδ T cells and intestinal RORγt IL-22 cells (NCR22 cells). Previous studies have proposed a critical role for NCR22 cells in mucosal barrier function through IL-22-mediated production of anti-bacterial peptides from intestinal epithelial c...

Abstract. For linear time-invariant (LTI) state space systems it is well-known that its asymptotic stability can be related to solution properties of the Lyapunov matrix equation according to so-called inertia theorems. The question now arises how analogous results can be obtained for LTI descriptor systems (singular systems, differential-algebraic equations). The stability behaviour of a LTI d...

Changes in cerebral blood flow (CBF) because of functional activation are used as a surrogate for neural activity in many functional neuroimaging studies. In these studies, it is often assumed that the CBF response is a linear-time invariant (LTI) transform of the underlying neural activity. By using a previously developed animal model system of electrical forepaw stimulation in rats (n = 11), ...

Lyapunov exponents and direction elds are used to characterize the time-scales and geometry of general linear time-varying (LTV) systems of di erential equations. Lyapunov exponents are already known to correctly characterize the time-scales present in a general LTV system; they reduce to real parts of eigenvalues when computed for linear time-invariant(LTI) systems and real parts of Floquet ex...

Two approaches to moment matching based model reduction of aperiodically sampled data systems are given. The term “aperiodic sampling” is used in the paper to indicate that the time between two consecutive sampling instants can take its value from a pre-specified finite set of allowed sampling intervals. Such systems can be represented by discrete-time linear switched (LS) state space (SS) mode...
