The demand for ever smaller and portable electronic devices has driven metal oxide semiconductor-based (CMOS) technology to its physical limit with the smallest possible feature sizes. This presents various size-related problems such as high power leakage, low-reliability, and thermal effects, and is a limit on further miniaturization. To enable even smaller electronics, various nanodevices including carbon nanotube transistors, graphene transistors, tunnel transistors and memristors (collectively called post-CMOSdevices) are emerging that could replace the traditional and ubiquitous silicon transistor. This book explores these nanoelectronics at the circuit and systems levels including modelling and design approaches and issues. Topics covered include self-healing analog and radio frequency circuits; on-chip gate delay variability measurement in scaled technology node; nanoscale finFET devices for PVT aware SRAM; data stability and write ability enhancement techniques for finFET SRAM circuits; low-leakage techniques for nanoscale CMOS circuits; thermal effects in carbon nanotube VLSI interconnects; lumped electro-thermal modeling and analysis of carbon nanotube interconnects; high-level synthesis of digital integrated circuits in the nanoscale mobile electronics era; SPICEless RTL design optimization of nanoelectronic digital integrated circuits; green on-chip inductors for threedimensional integrated circuits; 3D network-on-chips; and DNA computing. This book is essential reading for researchers, research-focused industry designers/developers, and advanced students working on next-generation electronic devices and circuits.
Utilities around the world are under increasing pressure to provide reliable and good quality power supply to their retail customers, and to reduce their operational costs. These concerns call for real time monitoring and control of the distribution system, which can be accomplished by deploying distribution automation (DA) systems, a key enabling technology for smart grids. This book provides a detailed description of all the major components of a DA system, including communication infrastructure and analysis tools. Topics covered include communication systems for distribution automation; load flow analysis; short circuit analysis; state estimation; feeder reconfiguration for loss reduction, service restoration, and load balancing; volt-var control; fault location; fault type identification; and economic analysis/cost benefit analysis. Concluding with an international case study (Enexis, one of the major Distribution System Operators in The Netherlands) showing how DA has been implemented in practice, this book is essential reading for researchers and advanced students working in power engineering and practitioners engaged in distribution automation, such as utility engineers, vendors, and consultant
In control theory, sliding mode control, or SMC, is a nonlinear control method that alters the dynamics of a nonlinear system by application of a discontinuous control signal that forces the system to "slide" along a crosssection of the system's normal behavior. This book describes recent advances in the theory, properties, methods and applications of SMC. The book is organised into four parts. The first part is devoted to the design of higher-order sliding-mode controllers, with specific designs presented in the context of disturbance rejection by means of observation and identification. The second part offers a set of tools for establishing different dynamic properties of systems with discontinuous right-hand sides. Time discretization is addressed in the third part. First-order sliding modes are discretized using an implicit scheme - higher-order slidingmode differentiators, typically used in output-feedback schemes, are discretized in such a way that the optimal accuracy of their continuous-time counterparts is restored. The last part is dedicated to applications. In the context of energy conversion, sliding-mode control is applied to variable-speed wind turbines, fuel cell coupled to a power converter, rugged DC series motors and rectifiers with unity power factor, and electropneumatic actuator. Finally, an event-triggered sliding-mode scheme is proposed for networked control systems subject to packet loss, jitter and delayed transmissions.
Optical MEMS are micro-electromechanical systems merged with micro-optics. They allow sensing or manipulating optical signals on a very small size scale using integrated mechanical, optical, and electrical systems and hold great promise specifically in biomedical applications, among others. This book describes the current state of optical MEMS in chemical and biomedical analysis with topics covered including fabrication and manufacturing technology for optical MEMS; electrothermally-actuated MEMS scanning micromirrors and their applications in endoscopic optical coherence tomography imaging; electrowetting-based microoptics; microcameras; biologically inspired optical surfaces for miniaturized optical systems; tuning nanophotonic cavities with nanoelectromechanical systems; quantum dot nanophotonics - micropatterned excitation, microarray imaging and hyperspectral microscopy; photothermal microfluidics; optical manipulation for biomedical applications; polymer-based optofluidic lenses; and nanostructured aluminum oxide-based optical biosensing and imaging. Bringing together topics representing the most exciting progress made and current trends in the field in recent years, this book is an essential addition to the bookshelves of researchers and advanced students working on developing, manufacturing or applying optical MEMS and other sensors.

Most physical systems possess parametric uncertainties or unmeasurable parameters and, since parametric uncertainty may degrade the performance of model predictive control (MPC), mechanisms to update the unknown or uncertain parameters are desirable in application. One possibility is to apply adaptive extensions of MPC in which parameter estimation and control are performed online. This book proposes such an approach, with a design methodology for adaptive robust nonlinear MPC (NMPC) systems in the presence of disturbances and parametric uncertainties. One of the key concepts pursued is the concept of setbased adaptive parameter estimation, which provides a mechanism to estimate the unknown parameters as well as an estimate of the parameter uncertainty set. The knowledge of non-conservative uncertain set estimates is exploited in the design of robust adaptive NMPC algorithms that guarantee robustness of the NMPC system to parameter uncertainty. Topics covered include: a review of nonlinear MPC; extensions for performance improvement; introduction to adaptive robust MPC; computational aspects of robust adaptive MPC; finite-time parameter estimation in adaptive control; performance improvement in adaptive control; adaptive MPC for constrained nonlinear systems; adaptive MPC with disturbance attenuation; robust adaptive economic MPC; setbased estimation in discrete-time systems; and robust adaptive MPC for discrete-time systems.
The main aims of power electronic converter systems (PECS) are to control, convert, and condition electrical power flow from one form to another through the use of solid-state electronics. This book outlines current research into the scientific modeling, experimentation, and remedial measures for advancing the reliability, availability, system robustness, and maintainability of PECS at different levels of complexity. Drawing on the experience of an international team of experts, this book explores the reliability of PECS covering topics including an introduction to reliability engineering in power electronic converter systems; anomaly detection and remaining-life prediction for power electronics; reliability of DC-link capacitors in power electronic converters; reliability of power electronics packaging; modelling for life-time prediction of power semiconductor modules; minimization of DC-link capacitance in power electronic converter systems; wind turbine systems; smart control strategies for improved reliability of power electronics system; lifetime modelling; power module lifetime test and state monitoring; tools for performance and reliability analysis of power electronics systems; fault-tolerant adjustable speed drive systems; mission profile-oriented reliability design in wind turbine and photovoltaic systems; reliability of power conversion systems in photovoltaic applications; power supplies for computers; and high-power converters. Reliability of Power Electronic Converter Systems is essential reading for researchers, professionals and students working with power electronics and their applications, particularly those specialising in the development and application of power electronic converters and systems.
