        abstract = {The problem of secure control design against denial of service (DoS) attacks for cyber-physical systems (CPS) is the focus of this work. We consider a continuous-time linear system with sampled linear state feedback control and a convex quadratic performance measure. DoS attacks place restrictions on the CPS, where a hostile party may jam packets between the sensor and controller, thereby causing instability and a decline in system performance. We assume that energy constraints limit the attacker's ability to launch DoS attacks for a finite amount of time and frequency. We develop an effective method to determine an upper bound on the performance deterioration caused by the DoS assault, based on the linear matrix inequality approach. Additionally, we suggest redesigning the controller to reduce this performance drop. Lastly, a simulation example demonstrates how to construct a secure controller and calculate the performance deterioration under a bounded DoS attack. The results of the simulation demonstrate that the designed controller successfully defends the stability and performance of the feedback loop against threats.},
