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.

The problem of identifying the hydrodynamic coefficients of a ship from free decay data was suggested by Dr. J. B. Roberts, who also made available the simulated data analysed in this paper. This work was partly supported by the National Maritime Institute Ltd.
