Web1 de jan. de 1988 · Observability is a global concept (Hermann and Krener, 1977) and a rigorous analysis of observability of nonlinear models is significantly more difficult than it is for linear systems (Mohler and Hwang, 1988). Thus, Hermann and Krener (1977) introduced the concept of local weak observability. Show abstract. WebThe fields of study he is best known for: Juergen Hahn spends much of his time researching Control theory, Nonlinear system, Observability, Estimation theory and Mathematical optimization. His work deals with themes such as Estimator, Computation and Reduction, which intersect with Control theory. His Nonlinear system research is mostly focused ... WebAbstract. Nonlinear adaptive observers that do not require knowledge of the dynamics of the system being observed are proposed. This objective is pursued by envisioning a linear-in-parameters adaptive law that allows one to estimate the system dynamics, which are assumed to be in observability canonical form, just from measurements of the output. ip\u0027s tagged as communist
