摘要：
This article considers the robust safety-critical control problem of an uncertain second-order nonlinear system subject to denial-of-service (DoS) attacks on the sensor-controller and controller-actuator channels. In order to handle the safety constraint described by a general nonlinear function, we first propose a governor function, regarded as a generalized barrier function, with additional properties. Then, a safety-critical control strategy is designed to guarantee the safety and stability of the closed-loop system. Finally, a combined time- and event-triggered sampling mechanism is further introduced to detect the randomly occurring DoS, and the latest sampled information is used to update the safety-critical control strategy once the signal can be received through the sensor-controller channel. Our sampled-data safety-critical control strategy effectively addresses both the safety-critical control and security control problems of nonlinear systems with parametric uncertainty.
