Abstract

This paper deals with observer design for generalized Hamiltonian systems and its applications. First, by using the systems’ structural properties, a new observer design method called Augment Plus Feedback is provided and two kinds of observers are obtained: non-adaptive and adpative ones. Then, based on the obtained observer, H control design is investigated for generalized Hamiltonian systems, and an observer-based control design is proposed. Finally, as an application to power systems, an observer and an observer-based H control law are designed for single-machine infinite-bus systems. Simulations show that both the observer and controller obtained in this paper work very well.
