TL;DR: A sum of squares (SOS) approach to the stability analysis of networked control systems (NCSs) incorporating time-varying delays and time- varying transmission intervals is presented and provides an automated method to address stability analysis problems in NCS.
Abstract: This paper presents a sum of squares (SOS) approach to the stability analysis of networked control systems (NCSs) incorporating time-varying delays and time-varying transmission intervals. We will provide mathematical models that describe these NCSs and transform them into suitable hybrid systems formulations. Based on these hybrid systems formulations we construct Lyapunov functions using SOS techniques that can be solved using LMI-based computations. This leads to several advantages: (i) we can deal with nonlinear polynomial controllers and systems, (ii) we can allow for nonzero lower bounds on the delays and transmission intervals in contrast with various existing approaches, (iii) we allow more flexibility in the Lyapunov functions thereby possibly obtaining improved bounds for the delays and transmission intervals than existing results, and finally (iv) it provides an automated method to address stability analysis problems in NCS.

TL;DR: In this paper, a method for designing robust MPC schemes that are self-optimizing in terms of disturbance attenuation is presented, which employs convex control Lyapunov functions and disturbance bounds.
Abstract: This paper presents a novel method for designing robust MPC schemes that are self-optimizing in terms of disturbance attenuation. The method employs convex control Lyapunov functions and disturbance bounds to optimize robustness of the closed-loop system on-line, at each sampling instant - a unique feature in MPC. Moreover, the proposed MPC algorithm is computationally efficient for nonlinear systems that are affine in the control input and it allows for a decentralized implementation.

TL;DR: In this article, the authors study linear passive electrical circuits mixed with ideal diodes and voltage/current sources within the framework of linear complementarity systems and investigate the existence and uniqueness of solution trajectories.
Abstract: In this paper we study linear passive electrical circuits mixed with ideal diodes and voltage/current sources within the framework of linear complementarity systems. Linear com- plementarity systems form a subclass of hybrid dynamical systems and as such questions about existence and uniqueness of solution trajectories are non-trivial and will be investigated here. The nature of the behaviour is analyzed and characterizations of the inconsistent states and explicit jump rules are presented in various equivalent forms. Moreover, the mode-selection problem (determining the discrete state as a function of the continuous state) will be discussed as well. The characterizations and rules will be in terms of quadratic programming problems and linear complementarity problems for which many numerical algorithms are available. As a consequence, the results obtained in this paper lead to numerical approaches for problems appearing in the event-driven simulation of a class of switched electrical circuits. A detailed example will illustrate the obtained results. RESUME. Dans le cadre des systemes lineaires complementaires, cet article porte sur l'etude de circuits electriques lineaires passifs, comportant des diodes ideales et des sources de ten- sion/courant. Les systemes lineaires complementaires constituent une sous-classe de systemes dynamiques hybrides, entrainant ainsi des problemes non triviaux d'existence et d'unicite des trajectoires qui seront plus particulierement abordes. Plusieurs formes d'equivalence sont uti- lisees pour analyser le comportement et identifier les etats incoherents ainsi que les regles de sauts explicites. Le probleme de la selection du mode discret en fonction de l'etat continu sera egalement traite. Les resultats obtenus fournissent des solutions numeriques aux problemes relatifs a la simulation evenementielle d'une classe de circuits electriques a commutation. Un exemple est donne pour illustrer ces resultats.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: This paper focuses on the stability analysis for switched linear systems under arbitrary switching, and highlights necessary and sufficient conditions for asymptotic stability.
Abstract: During the past several years, there have been increasing research activities in the field of stability analysis and switching stabilization for switched systems. This paper aims to briefly survey recent results in this field. First, the stability analysis for switched systems is reviewed. We focus on the stability analysis for switched linear systems under arbitrary switching, and we highlight necessary and sufficient conditions for asymptotic stability. After a brief review of the stability analysis under restricted switching and the multiple Lyapunov function theory, the switching stabilization problem is studied, and a variety of switching stabilization methods found in the literature are outlined. Then the switching stabilizability problem is investigated, that is under what condition it is possible to stabilize a switched system by properly designing switching control laws. Note that the switching stabilizability problem has been one of the most elusive problems in the switched systems literature. A necessary and sufficient condition for asymptotic stabilizability of switched linear systems is described here.

TL;DR: This paper proposes gradient descent algorithms for a class of utility functions which encode optimal coverage and sensing policies which are adaptive, distributed, asynchronous, and verifiably correct.
Abstract: This paper presents control and coordination algorithms for groups of vehicles. The focus is on autonomous vehicle networks performing distributed sensing tasks where each vehicle plays the role of a mobile tunable sensor. The paper proposes gradient descent algorithms for a class of utility functions which encode optimal coverage and sensing policies. The resulting closed-loop behavior is adaptive, distributed, asynchronous, and verifiably correct.
