Adaptive H ∞ $$ {H}_{\infty } $$ Control of Switched Cyber-Physical Systems Under Bilateral Cyber-Attacks

In this paper, the adaptive $H_{\infty }$ control problem is studied for the switched cyber-physical systems against bilateral cyber-attacks, which means the cyber-attacks occur both in sensor-to-controller channel and controller-to-actuator channel simultaneously. To reduce the influence of the bilateral cyber-attacks on system performance, the adaptive switched controller, the adaptive laws and the switching law dependent on the average dwell time method are co-designed. By resorting to constructed Lyapunov functions, the switched cyber-physical systems with bilateral cyber-attacks asymptotically converge to zero, and the adaptive $H_{\infty }$ control problem is solved. Finally, an aero-engine example is adopted to verify the effectiveness of the obtained results.
