Published in 2019 at "IFAC-PapersOnLine"

DOI: 10.1016/j.ifacol.2019.12.658

Abstract: Abstract Adaptive observers are recursive algorithms for joint estimation of both state variables and unknown parameters. Usually some persistent excitation (PE) condition is required for the convergence of adaptive observers. However, in practice, it may… read more here.
