Cyber‐Physical Systems (CPSs) are vulnerable to malicious network attacks due to tight combination of cyber‐system and physical system through a more open network communication. In this paper, a guaranteed cost control problem for a CPS under DoS jamming attacks is solved via both state feedback and output feedback methods. Specifically, an energy constraint DoS jammer with clear periodic attack strategy is proposed to attack wireless channel and to degrade the system performance. Without knowing the DoS jammer's attack strategy, a passive attack‐tolerant mechanism is established, and the corresponding state feedback and output feedback controllers are designed to achieve guaranteed cost control for the CPS with inherent packet dropouts under DoS jamming attacks. Finally, numerical examples are presented to demonstrate the effectiveness of the guaranteed cost controllers.
