Disturbance Attenuation in luenberger funciton observer designs - a parametric approach

摘要

This paper proposes a simple approahc for disturbance attenuation in the designs of Luenberger function observers for multivariable linear systems. The basic idea is to minimise the H_2 norm of the transfer function from disturbance to estimation error using the design freedom provided by a parametric approach for Luenberger observer design. Besides the design parameters, the observer poles are also optimised within desired regions on the left-half complex plane. With the proposed approach, additional specifications cna be easily acheived. Copyright ~direct C 2000 IFAC
