Abstract: | The stabilization problem is studied for networked control systems (NCSs) with time-varying delay that may be larger than one sampling period. By considering state feedback controllers, the closed-loop NCS is described as a switched delay system, which is then represented as an interconnected feedback system. A sufficient BIBO stability condition is derived for the closed-loop NCS by using the small gain theorem and the average dwell time technique. Design procedures for the BIBO stabilizing controllers are also presented. An example is given to demonstrate the effectiveness of the proposed method. |
