Book Description
"Control of Complex Systems: Structural Constraints and Uncertainty" focuses on control design under information structure constraints, with a particular emphasis on large-scale systems. The complexity of such systems poses serious computational challenges and severely restricts the types of feedback laws that can be used in practice. This book systematically addresses the main issues, and provides a number of applications that illustrate potential design methods, most which use Linear Matrix Inequalities (LMIs), which have become a popular design tool over the past two decades. Authors Aleksandar I. Zecevic and Dragoslav D. Siljak use their years of experience in the control field to also: Address the issues of large-scale systems as they relate to robust control and linear matrix inequalities Discuss a new approach to applying standard LMI techniques to large-scale systems, combining graphic-theoretic decomposition techniques with appropriate low-rank numerical approximations and dramatically reducing the computational effort Providing numerous examples and a wide variety of applications, ranging from electric power systems and nonlinear circuits to mechanical problems and dynamic Boolean networks "Control of Complex Systems: Structural Constraints and Uncertainty" will appeal to practicing engineers, researchers and students working in control design and other related areas.

Book Description
This dissertation deals with performance analysis and robust stabilizability verification of large-scale interconnected systems with respect to the class of linear time-invariant (LTI) decentralized controllers. These problems are formulated and tackled in four phases. First, an interconnected system with some unstable decentralized fixed modes (DFM) is considered. It is well-known that there is no stabilizing LTI decentralized controller for such a system; hence, a method is proposed to change the structure of the controller from decentralized to a proper overlapping form, with respect to which the system is stabilizable. This change in the control configuration is carried out by introducing some interactions among the isolated controllers, which leads to the elimination of the undesirable DFMs. The approach utilized in this thesis is based on the graph theory and, in fact, transforms the knowledge of the system into a number of bipartite graphs. A simple combinatorial algorithm is subsequently proposed to address the problem under consideration. The second problem investigated here is the characterization of all classes of LTI structurally constrained controllers with respect to which a given interconnected system has no fixed modes. Similar to the ideas and notions proposed to handle the preceding problem, an efficient method is presented to tackle the problem in this case. Since establishing a transmission link between a pair of local controllers would certainly incur cost, an implementation expenditure is attributed to each possible link. The proposed approach can also be used to attain the implementation cost associated with any suitable class of controllers obtained. As a by-product of this result, all classes of LTI stabilizing structurally constrained controllers with the minimum implementation cost can be characterized accordingly. A LTI structurally constrained control system is considered next, which is subject to parametric uncertainties. Moreover, a region of uncertainty in the form of a semi-algebraic set is envisioned to parametrize the range of variations for uncertain parameters. It is asserted that if the system is stabilizable via a given constrained controller at the nominal point, then it is almost always stabilizable at any operating point in the region of uncertainty. In other words, the points for which the system has some persistent fixed modes lie on an algebraic variety. A method is subsequently proposed to derive this variety. In the end, it is assumed that a stabilizing decentralized controller is designed for a pseudo-hierarchical large-scale system based on its hierarchical approximation. A LQ cost function is defined to evaluate the effectiveness of this indirect controller design for the system. It is shown that a reasonably tight upper bound on this performance index can be straightforwardly obtained by solving a constrained optimization problem with only three variables.

Book Description
This monograph couples output regulation with several recent developments in modern control theory. It re-examines output regulation theory to achieve a design of controllers that take into account the physical limiting characteristics of actuators such as saturation. The book provides a solution to the basic problem of finding a controller that achieves internal stabilization, results in a desired performance norm, and renders asymptotic tracking of a reference signal even in the presence of persistent disturbances.

Book Description
The Mohammed Dahleh symposium brought together leading researchers in several areas of engineering and science. Many of the presentations focused on new emerging research areas of key significance. These new areas have in common that the dynamics and control theory and methods provide the appropriate framework for the understanding of the corresponding phenomena, while at the same time providing many of the tools necessary for their application to relevant technologies. Examples of these opportunities include the areas of systems biology, quantum feedback and control, fluid dynamics, and control applications in nanotechnology. This collected volume demonstrates the importance of these emerging areas in the current research agenda in science and technology and shows that a unique opportunity exists to drastically extend the scope and impact of dynamics and control methods far beyond their traditional areas of application in engineering.

Book Description
Distributed Computer Control Systems: Proceedings of the IFAC Workshop, Tampa, Florida, U.S.A., 2-4 October 1979 focuses on the design, processes, methodologies, and applications of distributed computing systems. The selection first discusses the use of distributed control systems for facility energy management, including space conditioning control, plant design, central plant control, and system design. The book then takes a look at programming distributed computer systems with higher level languages. Topics include design of an application programming language for distributed computing systems; realization of a suitable programming language for distributed computing systems; and optimal structure and capabilities of an automatic control system. The text focuses on the similarities and differences of distributed computer control systems; transaction processing as an efficient conceptual framework for comparing and understanding distributed systems; and multi-processor approach for the automation of quality control in an overall production control system. The selection also deals with transaction processing in distributed control systems; parallel processing for distributed computer control systems; and design and development of distributed control systems. The book is a vital source of data for readers interested in distributed computing.

Book Description
This is the first comprehensive survey of control theory, covering the results of five decades of research in generative grammar. Among the issues discussed are: the distinction between raising and control, syntactic interactions with case, lexical determination of the controller, and phenomena like partial and implicit control.
