This paper is concerned with the guaranteed cost control for a class of networked control systems (NCSs)with denial-of-service (DoS) attack and time-varying communication delay. First, an uncertain switched systemmodel is proposed that is capable of capturing the DoS attack and the short time-varying delay simultaneously. Toachieve the exponential stability with a guaranteed cost performance level, a sufficient condition is derived in termsof matrix inequalities. In our work, the proposed design condition establishes several quantitative relations betweensystem performance and attack parameters. Moreover, the critical value of strong attack frequency is also obtained. Finally, a practical example is given to show the effectiveness of our results.
