Parameter bounds evaluation of Wiener models with noninvertible polynomial nonlinearities

摘要: In this paper a three stage procedure is presented for deriving parameters bounds of SISO Wiener models when the nonlinear block modeled by possibly noninvertible polynomial and output measurement errors are bounded. First, using steady-state input-output data, part bounded tight orthotope. Then, given estimated uncertain nonlinearity measurements collected exciting system with an input dynamic signal, on unmeasurable inner signal computed. Finally, such bounds, together noisy measurements, used bounding linear block.
