A design procedure for intermediate-order observer-estimators for linear discrete-time dynamical systems†
S.C. Iglehart, Cornelius T. Leondes · International Journal of Control · 1972
A design procedure is presented for observer-estimators which extends the results of Leondes and Novak for minimal-order observers (observer order l = n — m for an n-dimensional plant with m-dimensional measurement vector) to observers of intermediate order (n — m<l
