Parametric identification of transient signals

Abstract

The state-variable filter method of continuous-time parameter identification using a discrete-time identifier is extended to be applicable to signals composed of a transient response generated by a class of unforced nonlinear systems to which has been added a constant offset. The results are illustrated by estimating some hydrodynamic coefficients of a ship from free decay data; and some implications for self-tuning control are discussed. © 1984 Oxford University Press.
