Abstract :
By using a Luenberger reduced-order state observer and an auxiliary stable matrix, a modified parameterization of all linear observers is addressed. The factors of the observer parameterization are ensured to be stable and proper due to the use of the auxiliary stable matrix. Based on the proposed observer parameterization, the parameterization of estimation error dynamics is also developed.
