This book focuses on the observability of hybrid systems. It enables the reader to determine whether and how a hybrid system¿s state can be reconstructed from sometimes necessarily partial information. By explaining how available measurements can be used to deduce past and future behaviours of a system, the authors extend this study of observability to embrace the properties of diagnosability and predictability.H-systems shows how continuous and discrete dynamics and their interaction affect the observability of this general class of hybrid systems and demonstrates that hybrid characteristics are not simply generalizations of well-known aspects of traditional dynamics. The authors identify conditions for state reconstruction, prediction and diagnosis of the occurrence of possibly faulty states. The formal approach to proving those properties for hybrid systems is accompanied by simple illustrative examples. For readers who are interested in the use of state estimation for controller design, the book also provides design methods for hybrid state observers and covers their application in some industrial cases.The book¿s tutorial approach to the various forms of observability of hybrid systems helps to make H-systems of interest to academic researchers and graduate students working in control and to practitioners using control in an industrial environment.

This book explores how steam engine technology was transferred into nineteenth-century China in the second half of the nineteenth century by focusing on the transmission of knowledge and skills. It takes on the long-term problem in historiography that puts too much emphasis on politics but ignores the techno-scientific and institutional requirements for launching such an endeavor. It examines how translations broke linguistic and conceptual barriers and brought new a understanding of heat to the Chinese readership. It also explores how the Fuzhou Navy Yard¿s shipbuilding and training program trained Chinäs first generation of shipbuilding workers and engineers. It argues that conservatism against technology was not to blame for Chinäs slow development in steamship building. Rather, it was government officials¿ failure to realize the scale of institutional and techno-scientific changes required in importing and disperse new knowledge and skills.
