First, it covers the design of filters and their addition to the observer for reducing noise, a topic that has been so far neglected in the literature. Further, it describes the adaptive re-design of nonlinear observers to reduce the effect of parametric uncertainty. It discusses several limitations of classical methods, presenting a set of successfull solutions, which are mathematically formalised through Lyapunov stability analysis, and in turn validated via numerical simulations. In the second part of the book, two applications of the adaptive nonlinear observers are described, such in the estimation of the liquid water in a hydrogen fuel cell and in the solution of a common cybersecurity problem, i.e. false data injection attacks in DC microgrids. All in all, this book offers a comprehensive report on the state-of-the-art in nonlinear observer design for energy systems, including mathematical demonstrations, and numerical and and experimental validations. 001476557 588__ $$aOnline resource; title from PDF title page (SpringerLink, viewed September 6, 2023). 001476557 650_0 $$aObservers (Control theory) 001476557 650_0 $$aParameter estimation. 001476557 650_0 $$aFeedback control systems. 001476557 655_0 $$aElectronic books. 001476557 77608 $$iPrint version:$$aCecilia, Andreu$$tAdvances in Nonlinear Observer Design for State and Parameter Estimation in Energy Systems$$dCham : Springer,c2023$$z9783031389238 001476557 830_0 $$aSpringer theses,$$x2190-5061 001476557 852__ $$bebk 001476557 85640 $$3Springer Nature$$uhttps://univsouthin.idm.oclc.org/login?url=https://link.springer.com/10.1007/978-3-031-38924-5$$zOnline Access$$91397441.1 001476557 909CO $$ooai:library.usi.edu:1476557$$pGLOBAL_SET 001476557 980__ $$aBIB 001476557 980__ $$aEBOOK 001476557 982__ $$aEbook 001476557 983__ $$aOnline 001476557 994__ $$a92$$bISE
