Static output feedback quantized dissipative security control of singular hybrid systems subject to multiple cyber attacks: A dynamic-memory event-triggered strategy

Abstract

This paper researches the problem of dynamic-memory event-triggered quantized dissipative security control for singular Markovian jump systems (SMJSs) subject to multiple cyber attacks, which comprise denial of service (DoS) attacks and multichannel deception attacks. By employing a set of historically released packets, a dynamic-memory event-triggered strategy is developed subject to DoS attacks which can decrease the occupancy rate of network communication bandwidth and achieve desired dissipative control performance. Furthermore, the closed-loop SMJSs are established by a switched system model on account of the simultaneous appearance of DoS attacks and deception attacks By constructing an improved mode-dependent piecewise Lyapunov–Krasovskii functional and applying singular value decomposition technique, the criteria of exponential admissibility and strict dissipativity for the controlled SMJSs are acquired by right of linear matrix inequalities. The idiographic form of the static output feedback quantized controller is expressed via a valid decoupling method. Finally, the validity of the proposed approach is testified by a numerical example and direct current motor driven load.
