摘要：AbstractIn this note, we address the problem of parameter identification of nonlinear, input affinedissipativesystems. It is assumed that the supply rate, the storage and the internal dissipation functions may be expressed asnonlinearly parameterizedregression equations where the mappings (depending on the unknown parameters) satisfy amonotonicitycondition—this encompasses a large class of physical systems, including passive systems. We propose to estimate the system parameters using the “power-balance” equation, which is the differential version of the classical dissipation inequality, with a new estimator that ensures global, exponential, parameter convergence under the very weak assumption ofinterval excitationof the power-balance equation regressor. The benefits of the proposed approach are illustrated with an example.
