The paper presents stability analysis of a Networked Control System (NCS) with bounded uncertain time-varying network induced delays. The system with uncertain delays is modeled as an uncertain system with norm-bounded uncertainties. With this consideration stability improving performance of classical Smith Predictor (SP) is investigated. Linear Matrix Inequality (LMI) conditions have been derived to explore the stability region in the controller gain and delay parameter plane. The proposed stability analysis is veriļ¬ed through simulations considering three examples.
