This paper is concerned with output feedback stabilization of a networked control system in the discrete-time domain. First, a logical zero-order-hold is introduced to select the newest data packets to drive the plant, with which network-induced delays and data packet dropouts can be expressed explicitly. Second, an auxiliary vector-valued function is introduced to establish a novel finite-sum inequality,...
This paper is concerned with stability of linear discrete time-delay systems. Note that a tighter estimation on a finite-sum term appearing in the forward difference of some Lyapunov functional leads to a less conservative delay-dependent stability criterion. By using Abel lemma, a novel finite-sum inequality is established, which can provide a tighter estimation than the ones in the literature for...
This paper focuses on the stability analysis of a discrete-time linear system with an interval-like time-varying delay in the state. A novel inequality for finite-sum Σj=(r1)(r2)-1ωT(j)Rω(j) is first established, where r1 and r2 are integers or integer-valued functions and R is a symmetric definite positive matrix. One of advantages of this inequality is that the factor r2-r1 appears in the estimation...
