Abstract [en]

The authors describe a procedure for estimating parameters in multivariable linear systems, parameterized in pseudo-observability state-space canonical forms. The procedure is based on a standard four-stage instrumental variable method and subsequent operations in the Hankel matrix of estimated impulse responses. The main use of the procedure is for initialization of maximum likelihood/prediction error estimation methods.
