Yang, Fuyu; Wilde, Richard W. Observers for linear systems with unknown inputs. (English) Zbl 0646.93013 IEEE Trans. Autom. Control 33, No. 7, 677-681 (1988). A direct design procedure of a full-order observer for a linear system with unknown inputs is presented, using straightforward matrix calculations. Some examples are given; in these examples a reduced-order observer is also derived. It is shown that this may restrict the rate of convergence of some state estimates.
