This study is concerned with dynamic output feedback (DOF) H ∞ control for continuous‐time networked control systems (NCSs). The packet dropouts and network‐induced delays in the sensor‐to‐controller channel, and network‐induced delays in the controller‐to‐actuator channel are taken into account. A linear estimation‐based method is proposed to estimate the measurement output, and the non‐uniform distribution characteristic of the measurement output arrival instant is taken into full consideration to establish a new model for the considered NCSs. Based on the newly established model and a new Lyapunov functional, the problem of DOF controller design is studied. A numerical example is given to illustrate the effectiveness of the proposed DOF controller design.
