A reduced order observer for descriptor systems. (English) Zbl 0598.93006

A reduced order observer is analyzed for so-called generalized state space (or descriptor) systems. Based on the staircase form for generalized state space models, a recursive algorithm is presented to construct a reduced order observer for a given observable descriptor system. In the algorithm only the eigenfrequencies of the observer have to be specified.
