The recursive least-squares (RLS) identiΓΏcation algorithm is often extended with exponential forgetting as a tool for parameter estimation in time-varying stochastic systems. The statistical properties of the parameter estimates obtained from such an extended RLS-algorithm depend in a non-linear way
In this paper a modi"ed version of the standard least-squares algorithm is presented. The aim is to use the proposed modi"ed LS algorithm in linear time-varying systems. The proposed modi"cation involves the addition of extra terms to both the parameter estimates' and the covariance's update laws. W
