“…Recently output dynamic feedback design for NCS has been proposed using Linear Matrix Inequalities (LMI), based on the design procedure introduced by C. Scherer in [21] or on the elimination lemma. The output dynamic feedback may be independent with respect to the timevarying delay [8,10,18], or time-varying delay dependent: [22] considers two delays (back and forth), [17] a global time-varying delay less than the sampling period and [16] a global and bounded time-varying delay multiple of the sampling period.…”

The stabilization of a network controlled system including a global time-varying delay is investigated in this note. This delay is considered to be unknown but it is assumed that a bounded error estimate is available. The exponential uncertainty induced by the time-varying delay is decomposed into a sum of a polytopic term and an uncertain bounded term. Sufficient conditions to design a dynamic output feedback controller depending on estimate of the time-varying delay are proposed as LMIs. An illustration shows how our methodology enlarges the design techniques of the literature.
