Abstract
An on-line (or recursive) parameter estimation scheme based on a physical m odel is presented. Tracking of time-varying parameters is achieved by the u se of a forgetting factor in the standard formulation. A new scheme for ada pting the forgetting factor is proposed and validated on time-data from bot h simulated and experimental systems. (C) 2000 Academic Press.
