Multi-factorial rate bumpless output regulation of switched systems against multiple deception attacks: The dissipativity framework

Abstract

Multiple deception attacks (MDAs) cause multiple bumps of the switched system (SS) state rate on dual sensor and transmission networks. The conflicts among uncorrelated amplitude limits are elicited by independently using existing rate bumpless transfer control (BTC) methods to suppress multiple bumps of the system state rate elicited by MDAs. A new multi-factorial rate BTC method is proposed limiting the total amplitude of multiple bumps elicited by MDAs, and balancing transient performances of the output regulation (OR) for the SS, thereby improving its steady-state performance. The anti-sensor-attack event-triggering mechanisms (ASAETMs) compute the error using data on the forged adjacent sensor nodes and dynamically adjust the threshold based on the attack probability to resist MDAs that can tamper with adjacent relation and data transmission on dual sensor networks. The utilization of the dissipativity theoretical framework establishes a quantitative link between the external data transfer, the solvability conditions of the OR control scheme, and levels of energy dissipation within the SS. Finally, the methods are applied to an aircraft engine for verification.
