Static Output-Feedback Based Fault-Tolerant Control Algorithm for Intelligent Connected Vehicles Under DoS Attacks

Cyber-attacks have been thought as one of the most critical problems of intelligent connected vehicle systems (ICVS) because of the network vulnerability of ICVS structures. Denial of Service (DoS) attacks is one category of Cyber-attacks, which can consequently disrupt the data availability during signals transmission and thus causes communication interruption. Handling instability of ICVS that is under DoS attacks attaches significant importance to ICVS security. In the paper, the nonlinear dynamics of ICVS system is reformulated in a form of fuzzy Takagi-Sugeno (TS) model with two antecedent variables. Then an effective control mode combining feedforward and feedback is proposed to ensure tracking performance of signals sent by the previous vehicle. Based on the feedback control, a fault-tolerant algorithm is proposed in the form of switching input packets, which can guarantee an asymptotic stability of ICVS dynamics.
