This study investigates the cyber‐security control problem of a networked switched system. Firstly, a joint probabilistic model is utilised to characterise the communication failure caused by the jamming attack and random packet loss. Then the attention is focused on designing an observer based controller that can generate the control input using the last successfully received system output. After that, with the average dwell time scheme, sufficient conditions are derived to ensure the almost sure asymptotical stability of the overall‐system with stable and unstable subsystems. In addition, an approach is developed to obtain the feasible solution of state feedback and observer gains. Finally, a simulation example implies the effectiveness of the authors' methods.
