Co-Design of a Switching-Type Control Scheme for Nonlinear Networked Systems With Protocol-Based Communication and Its Application to Circuits

This article investigates the resilient security control problem of nonlinear network systems under randomly activated deception attacks and a two-phase data transfer mechanism (TP-DTM). Initially, in order to solve the problem of high conservatism caused by the one-order free-weighting matrix (OFM) method in previous research results, this study introduces a high-order multi-mode switching free-weighting matrix (HMSFM) mechanism to establish free-weighting matrix groups under various switching modes, At the same time, sometime-varying balance matrices (TVBMs) are proposed to cooperate with HMSFM to collect proprietary features about each switching mode. Furthermore, in the context of the system subjected to deception attacks, a TP-DTM employing adaptive event-triggered mechanism (AETM) and round robin (RR) protocol is proposed to alleviate the impact of limited communication resources. Then, considering the above factors, the asymptotic stability of the augmented fuzzy system can be guaranteed under the given sufficient criteria. Consequently, a numerical example and a tunnel diode circuit example are executed to verify the advancement of the developed results.
