A graduate-level textbook, Hybrid Dynamical Systems provides an accessible and comprehensive introduction to the theory of hybrid systems. It emphasizes results that are central to a good understanding of the importance and role of such systems. The authors have developed the materials in this book while teaching courses on hybrid systems, cyber-physical systems, and formal methods.This textbook helps students to become familiar with both the major approaches coloring the study of hybrid dynamical systems. The computer science and control systems points of view – emphasizing discrete dynamics and real time, and continuous dynamics with switching, respectively – are each covered in detail.The book shows how the behavior of a system with tightly coupled cyber- (discrete) and physical (continuous) elements can best be understood by a model simultaneously encompassing all the dynamics and their interconnections. The theory presented is of fundamental importance in a wide range of emerging fields from next-generation transportation systems to smart manufacturing.Features of the text include:extensive use of examples to illustrate the main concepts and to provide insights additional to those acquired from the main text;chapter summaries enabling students to assess their progress;end-of-chapter exercises, which test learning as a course proceeds;an instructor’s guide showing how different parts of the book can be exploited for different course requirements; anda solutions manual, freely available for download by instructors adopting the book for their teaching.Access to MATLAB and Stateflow is not required but would be beneficial, especially for exercises in which simulations are a key tool.

This SpringerBrief investigates the performance of semi-blind independent component analysis (ICA) based equalization and carrier frequency offset estimation approaches (CFO) for a number of orthogonal frequency division multiplexing (OFDM) based wireless communication systems. It provides a comprehensive overview of the challenges of channel equalization and frequency synchronization for different wireless systems. The authors present the wireless communication channel and system models. Key existing CFO estimation methods are reviewed, along with a number of the training based and non-training based (blind) channel estimation methods. This is followed by a study of ICA and its applications to OFDM-based wireless communication systems. Later chapters provide a detailed description of recent research on semi-blind CFO estimation and ICA based equalization approaches for various wireless communication systems including multiple-input multiple-output (MIMO) OFDM and coordinated multipoint (CoMP) systems. Semi-blind CFO estimation and equalization structures provide a spectrum-efficient and high-performance solution for high speed wireless communications. This book is suitable for postgraduate students, researchers or professionals in the area of wireless communications.

The methods for hybrid systems are distributed across a wide spectrum, ranging from methods known in the discrete (cyber-)domain at one end, to traditional approaches for the continuous physical systems at the other. Rooted at opposite ends, both computer scientists and control theorists have made significant contributions to the field of hybrid systems by extending traditional methods from the traditional discrete or continuous domain to deal with hybrid systems. However, in general, there has been little work on integrating methods from these two domains. This is possibly because the formal methods pursued in computer science traditionally lie in the realm of discrete mathematics, while control theory approaches lie mainly in the realm of continuous mathematics.A noticeable trend in the recent hybrid system literature emphasizes the synthesis of hybrid controllers for continuous or hybrid dynamical systems to satisfy complicated temporal logic specifications. This is known as symbolic control or hybrid supervisory control, which can be seen as a crosstalk between these two schools of thoughts. Hybrid Dynamical Systems balances the emphasis on methods from both computer science and control theory, and gives the readers a complete picture of the whole field of hybrid dynamical systems. As well as providing a concise overview for a researcher in the field, the tutorial style makes it suitable for use in a course and by students.
