Stabilizability and asymptotic stabilizability of switching systems is characterized in terms of the existence of controlled invariant sets and domains of attraction. Then the classical Kalman decomposition for linear dynamical system is extended to switching systems. This shows that the core issue for solving the stabilizability problem for switching systems is the stability of an autonomous (...

This paper proposes a switching adaptive control for trajectory tracking of unmanned aircraft systems. The switching adaptive control method is designed to overcome the wind disturbance and achieve a proper tracking performance for control systems. In the suggested system, the wind disturbance is regarded as a finite set of uncertainties; a controller is designed for each uncertainty, and a per...

We define observability and detectability for linear switching systems as the possibility of reconstructing and respectively of asymptotically reconstructing the hybrid state of the system from the knowledge of the hybrid outputs for a suitable choice of the control input. We derive a necessary and sufficient condition for observability that can be verified computationally. A characterization o...

In this paper we study switching systems, a subclass of hybrid systems, and we address different positivity questions: we analyze systems where state variables evolve while remaining non–negative independently from the control chosen and external events actions (systems in this class are usually called positive systems), and systems where a control strategy can be designed in order to maintain ...

In this paper we propose a method to create discrete abstraction of state space behavior for continuous-time systems based on gradient analysis of the system dynamics. Then we describe how to use such a discrete model to design a supervisory controller for a given safety spiflication for the system. Finally we provide an entropy measure of nondeterminism, which can be used to evaluate the quali...

Switching systems are an important mathematical formalism when dealing with Cyber-Physical Systems (CPSs). In this paper we provide conditions for the exact reconstruction of the initial discrete state of a switching system, when only the continuous output is measurable, and the discrete output signal is not available. In particular, assuming that the continuous input and output signals may be ...

Congestion avoidance is an important traffic engineering task, which can be performed by making use of loadbalancing technique when a link is over loaded or failure of link occur in Multi-Path Switching Systems . Multipath Switching Systems are capable of transferring high rate data in networks. As preserving the inter flow packet orders while avoiding congestion is a major issue in considerati...

In this paper we consider the asymptotic stability of a class of discrete-time switching linear systems, where each of the constituent subsystems is Schur stable. We first present an example to motivate our study, which illustrates that the bilinear transform does not preserve the stability of a class of switched linear systems. Consequently, continuous time stability results cannot be transfor...

Switching devices are key components in any power electronic circuit or system as they control and limit the flow of power from the source to the load. Their power level requirements (current & voltage) and switching frequency are continually increasing in the power electronic industry, and this demands larger and faster switching devices. This paper will focus on the development of high power ...

The functionality of computer memory elements is currently based on multi-stability, driven either by locally manipulating the density of electrons in transistors or by switching magnetic or ferroelectric order. Another possibility is switching between metallic and insulating phases by the motion of ions, but their speed is limited by slow nucleation and inhomogeneous percolative growth. Here w...
