ROBUST STATIC OUTPUT FEEDBACK FOR DISCRETE-TIME SYSTEMS - LMI APPROACH 1

Two novel linear matrix inequality (LMI) based procedures to receive a stabilizing robust output feedback gain are presented, one of them being a modification of previous results of Oliveira et al., [5]. The proposed robust control law stabilizes the respective uncertain discrete-time system described by a polytopic model with guaranteed cost. The obtained results are compared with other LMI results from literature and illustrated on an example.
