Discrete-Time Systems comprehend an important and broad research field. The consolidation of digital-based computational means in the present, pushes a technological tool into the field with a tremendous impact in areas like Control, Signal Processing, Communications, System Modelling and related Applications. This fact has enabled numerous contributions and developments which are either genuinely original as discrete-time systems or are mirrors from their counterparts of previously existing continuous-time systems. This book attempts to give a scope of the present state-of-the-art in the area of Discrete-Time Systems from selected international research groups which were specially convoked to give expressions to their expertise in the field. The works are presented in a uniform framework and with a formal mathematical context. In order to facilitate the scope and global comprehension of the book, the chapters were grouped conveniently in sections according to their affinity in 5 significant areas. The first group focuses the problem of Filtering that encloses above all designs of State Observers, Estimators, Predictors and Smoothers. It comprises Chapters 1 to 6. The second group is dedicated to the design of Fixed Control Systems (Chapters 7 to 12). Herein it appears designs for Tracking Control, Fault-Tolerant Control, Robust Control, and designs using LMI- and mixed LQR/HThe third group includes Adaptive Control Systems (Chapter 13 to 15) oriented to the specialities of Predictive, Decentralized and Perturbed Control Systems. The fourth group collects works that address Stability Problems (Chapter 16 to 20). They involve for instance Uncertain Systems with Multiple and Time-Varying Delays and Switched Linear Systems. Finally, the fifth group concerns miscellaneous applications (Chapter 21 to 27). They cover topics in Multitone Modulation and Equalisation, Image Processing, Fault Diagnosis, Event-Based Dynamics and Analysis of Deterministic/Stochastic and Multidimensional Dynamics. We think that the contribution in the book, which does not have the intention to be all-embracing, enlarges the field of the Discrete-Time Systems with signification in the present state-of-the-art. Despite the vertiginous advance in the field, we think also that the topics described here allow us also to look through some main tendencies in the next years in the research area.
