This study is concerned with the problem of dual communication channels sharing‐based network‐induced delay and packet dropout compensation for continuous‐time networked control systems (NCSs). By introducing the dual communication channels sharing‐based compensation method, a new closed‐loop model for continuous‐time NCSs, which can receive more than one control input during a control input updating time interval, is established. Based on the newly established model and a new Lyapunov functional, an effective controller design criterion is derived to optimise the H ∞ performance of the considered systems. Even for NCSs without considering network‐induced delay and packet dropout compensation, the newly derived controller design method is also applicable. Two numerical examples are given to illustrate the merits and effectiveness of the proposed compensation method.
