Time-Varying Sliding Modes for Second and Third Order Systems

By: Andrzej Bartoszewicz,Aleksandra Nowacka-Leverton

A principal objective of control engineering is to design control systems which are robust with respect to external disturbances and modelling uncertainty. This objective may be well achieved using the sliding mode technique - which is the main subject of this monograph. More precisely, “Time-Varying Sliding Modes for Second and Third Order Systems” focuses on only one, but very important aspect of the sliding mode system design, i.e. the problem of the sliding plane selection. In this self-contained monograph, the main notions and concepts used in the field of variable structure systems and sliding mode control are presented before in the main part the issue of the switching surface design is discussed. This is done by considering two standard plants, which are very often encountered in the control engineering practice: the second and the third order nonlinear and possibly time-varying systems.

Congestion Control in Data Transmission Networks

Sliding Mode and Other Designs

By: Przemysław Ignaciuk,Andrzej Bartoszewicz

Congestion Control in Data Transmission Networks details the modeling and control of data traffic in communication networks. It shows how various networking phenomena can be represented in a consistent mathematical framework suitable for rigorous formal analysis. The monograph differentiates between fluid-flow continuous-time traffic models, discrete-time processes with constant sampling rates, and sampled-data systems with variable discretization periods. The authors address a number of difficult real-life problems, such as: optimal control of flows with disparate, time-varying delay; the existence of source and channel nonlinearities; the balancing of quality of service and fairness requirements; and the incorporation of variable rate allocation policies. Appropriate control mechanisms which can handle congestion and guarantee high throughput in various traffic scenarios (with different networking phenomena being considered) are proposed. Systematic design procedures using sound control-theoretic foundations are adopted. Since robustness issues are of major concern in providing efficient data-flow regulation in today’s networks, sliding-mode control is selected as the principal technique to be applied in creating the control solutions. The controller derivation is given extensive analytical treatment and is supported with numerous realistic simulations. A comparison with existing solutions is also provided. The concepts applied are discussed in a number of illustrative examples, and supported by many figures, tables, and graphs walking the reader through the ideas and introducing their relevance in real networks. Academic researchers and graduate students working in computer networks and telecommunications and in control (especially time-delay systems and discrete-time optimal and sliding-mode control) will find this text a valuable assistance in ensuring smooth data-flow within communications networks.

Conrad’s European Context

By: Andrzej Busza

On account of Conrad’s tragic and fascinating life before he became a writer, critics have usually offered a historical account of his early Polish years. Less attention has been paid to the cultural and literary background of that period and its subsequent influence. In fact, initially that influence was largely ignored. My aim has been not only to rectify that deficiency but to broaden the scope of the issue. In addition to dealing with his Polish background, the book also relates Conrad’s writing to other European literary traditions, notably French and Russian. Exploring the extraordinary geographical and historical range of Conrad’s fictional world, the book examines the rhetorical and narrative strategies employed in its vividly dramatic as well as psychologically insightful depictions.

The Birth of a Stereotype

Polish Rulers and Their Country in German Writings C. 1000 A.D.

By: Andrzej Pleszczynski

Presenting the image of Poland created in Germany in the earliest period of existence of the Piast state (963-1034) this book identifies its context and describes the political and cultural relation between the Polish rulers and German élites of that time.

The Archaeology of Early Medieval Poland

Discoveries – Hypotheses – Interpretations

By: Andrzej Buko

This is the first academic book which concentrates on the discoveries of medieval date (6th- 13th centuries) from the territory of modern Poland. The book covers the principal research questions, such as the origins of the Slavs, societies of the proto-state period and the origins of the Polish state. The volume also includes a discussion of the most interesting, sometimes controversial, archaeological discoveries or issues. These include pagan Slavonic holy places, the monumental mounds of Little Poland, the first traces of medieval writing, exceptional strongholds, the origins of Polish towns, rural landscapes, archaeology of the oldest monastic complexes, and the question of locals and aliens viewed through archaeological evidence and many other topics. The book is meant mainly for students, archaeologists and historians. It can also be useful for a wider audience interested in the history and archaeology of central Europe. In November 2006 "The Archaeology of Early Medieval Poland" received the KLIO Award from the Association of Polish History Publishers.
