A consistent parameter estimator for excitation control of synchronous generators

Deals with the problem of identification of the network parameters and the desired equilibrium in applications of excitation control for synchronous generators. Our main contribution is the construction of a new nonlinear identifier that provides asymptotically consistent estimates (with guaranteed transient bounds) of the line impedance and the equilibrium for the classical three-dimensional flux-decay model of a single generator connected to an infinite bus. The behavior of the scheme is illustrated in two simulated case studies with the interconnection and damping assignment passivity-based controller previously proposed by the authors.
