Linear Port Hamiltonian Systems on Infinite dimensional Spaces This book provides a self contained introduction to the theory of infinite dimensional systems theory and its applications to port Hamiltonian systems. The textbook starts with elementary known results then progresses smoothly to advanced topics in current research. Many physical systems can be formulated using a Hamiltonian framework leading to models described by ordinary or partial differential equations. For the purpose of control and for the interconnection of two or more Hamiltonian systems it is essential to take into account this interaction with the environment. This book is the first textbook on infinite dimensional port Hamiltonian systems. An abstract functional analytical approach is combined with the physical approach to Hamiltonian systems. This combined approach leads to easily verifiable conditions for well posedness and stability. The book is accessible to graduate engineers and mathematicians with a minimal background in functional analysis. Moreover the theory is illustrated by many worked out examples. 1 Introduction 2 State Space Representation. 3 Controllability of Finite Dimensional Systems 4 Stabilizability of Finite Dimensional Systems 5 Strongly Continuous Semigroups 6 Contraction and Unitary Semigroups 7 Homogeneous Port Hamiltonian Systems 8 Stability 9 Stability of Port Hamiltonian Systems 10 Inhomogeneous Abstract Differential Equations and Stabilization 11 Boundary Control Systems 12 Transfer Functions 13 Well posedness A Integration and Hardy spaces Bibliography Index. .
