| Abstract: | Based on the strongly positive real lemma, this paper presents a solution to the general strongly positive real control problem for linear time invariant discrete time systems using linear matrix inequality approach. The necessary and sufficiency conditions for the existence of an output feedback controller of any order are given. It is proved that for a general discrete time systems, there is a strongly positive real controller if and only if three LMIs have a solution and there is a low order controller if and only if the LMIs constrained by a rank condition have a solution. |
