Control of Cyber-Physical Systems
Guest Editors: Karl H. Johansson, George J. Pappas, Paulo Tabuada, Claire J. Tomlin

Cyber-physical systems are engineered systems whose operations are monitored, coordinated, controlled, and integrated by computing and communication cores interacting with the physical environment. Cyber-physical systems transform how we interact with the physical world just like the Internet has transformed how we interact with one another. Advances in this field will have an enormous societal impact and economic benefit in areas such as energy, transportation, manufacturing, health, agriculture and many more.

Relaxation Methods in Identification and Estimation Problems
Guest Editors:
Diego Regruto, Fabrizio Dabbane, Daniel E. Rivera

The subject of system identification has a long history, and it still remains one of the most active fields of research in the control community. In the literature at large, particular attention has been devoted identification in recent years to the convexification of estimation problems, and convexification has become one of the major topics in system identification. A number of different approaches have recently emerged in the optimization community to address the problem of approximating the global solution of some classes of nonconvex optimization problems. The common idea behind all these approaches is to construct specific convex relaxations, which are guaranteed to converge, under proper assumptions and conditions, to the global optima of the original nonconvex problem.

Control of Quantum Mechanical Systems
Guest Editors: Claudio Altafini, Anthony M. Bloch, Pierre Rouchon

Moving beyond the mere observation of atomic or molecular scale events to their active control is a long standing dream, which only in recent years has become a really fruitful area of experimental investigation in different scientific disciplines ranging from Chemical Reaction Dynamics to Quantum Optics, from Magnetic Resonance to Quantum Information Processing. The reasons are diverse, from the technological advances enabling the monitoring and manipulation of atoms, molecules and spins at the quantum scale, to the discovery of the potential superiority of quantum computing devices over classical ones. Advances in the areas of attosecond laser coherent control, nuclear and electron magnetic resonance spectroscopy, optical and solid state devices all involve some form of active control of quantum dynamics. Similarly, the recent progress in the science of quantum information has added a new perspective to the use of quantum dynamics for the purpose of computing, communications and information storage. All these technologies involve exercising control over quantum mechanical systems.

Wireless Sensor and Actuator Networks
Guest Editors: Jiming Chen, Karl H. Johansson, Stephan Olarlu, Ioannis Ch. Paschalidis, Ivan Stojmenovic

Wireless Sensor Networks (WSNs), in their various shapes and forms, have greatly facilitated and enhanced the automated, remote, and intelligent monitoring of a large variety of physical systems. These networks consist of a large number of typically small devices, each incorporating sensing, processing, and wireless communications capabilities. Their use has penetrated a plethora of application domains from industrial and building automation, to environmental, wildlife, and health monitoring.

Positive Polynomials in Control
Guest Editors: Graziano Chesi, Didier Henrion

While the passage to the next generation of methods involving positive non-polynomial functions is still far, the development of theory and tools based on positive polynomials has reached a solid level. This special issue aims to identify to what extent positive polynomials are currently exploited and can be further exploited in control systems, attempting to provide a complete overview of their application area as well as outline their potentialities and limitations in both theoretical and practical uses. The target of this collection of works on positive polynomials is to identify the state of the art of this young and promising field.

Joint Special Issue on Systems Biology
Guest Editors: Mustafa Khammash, M. Vidyasagar, Claire Tomlin

Systems biology can be defined as the study of organisms, or parts of an organism, viewed as an interconnection of various subsystems serving a variety of biological functions. A biological system can be studied at several levels of complexity and aggregation, such as genes, proteins, pathways, and cells. Central to the study of systems biology is the notion of dynamics, one of the characteristics that distinguishes it from computational biology. This joint special issue consists of papers that cover fundamental concepts and issues in systems biology, including analysis of biological networks, dynamics of signaling and regulatory networks, dynamic modeling and identification of biological networks, and modeling, design, and construction of biological circuits.

Symbolic Methods for Complex Control Systems
Guest Editors: Magnus Egerstedt, Emilio Frazzoli, George J. Pappas

This special issue targets a better understanding and design of continuous signal to finite symbol mappings for control purposes. These include abstracting continuous dynamics to symbolic control descriptions, instruction selection and coding in finite-bandwidth control applications, and applying formal language theory to the continuous systems domain.

Control System Identification
Guest Editors: Lennart Ljung, Antonio Vicino

The topic of System Identification has been a surprisingly vivid and resilient research area in the control community over many years. Thirteen years after the publication of a 1992 special issue edited by Robert Kosut, Graham Goodwin and Mike Polis, this new special issue gives a broad perspective of the state of the art on the subject of system identification of linear as well as non-linear models.

Networked Control Systems
Guest Editors: Panos Antsaklis, John Baillieul

This special issue deals with systems comprised of actuators, sensors, and controllers whose operation is coordinated through some form of communication network. The system elements are typically spatially isolated from one another, operating in an asynchronous manner and communicating over a wide area via both wired and wireless links. The topics covered in the issue include studying the relationship between closed loop stability and communications constraints on the feedback channels, ad hoc network formation and mobility, consensus problems for networks of dynamic agents with fixed and switching topologies, and information flow and stability of distributed control in autonomous vehicle formations.

This special issue presents recent advances in the Mathematics of Finance and related new problems in stochastic systems and control theory. Topics covered include the study of arbitrage, hedging, pricing, consumption/investment optimization, incomplete and/or constrained markets, equilibrium, differential information, and the term-structure of interest rates.
