Event-Triggered Security Control for Connected Vehicle Platoon System Subject to Deception Attacks

An attack-resilient event-triggered secure control approach is presented for the platoon system composed of connected vehicles that are exposed to deception attacks. Firstly, a new discrete linear model is developed for the system of vehicle platooning, including the distance error, the relative velocity, and acceleration as the state vector. Secondly, considering the stochastic occurrence of deception attacks at the sensor and controller ends of vehicles, the probabilistic occurrence of the deception attack is represented by two sets of Bernoulli stochastic variables. In an effort to decrease the communication resources consumption, an event triggering mechanism is used to determine the transmission of vehicle state information between the sensor and controller. Then, the sufficient condition is constructed through utilizing the Lyapunov theory of stability, which can guarantee the stabilization of interconnected vehicles in the platoon, and the parameters related to the controller and event-triggered mechanism are provided based on the solution of linear matrix inequalities (LMIs). Eventually, the usefulness of the suggested scheme in ensuring control performance while saving computational and communication resources is verified through the comparative experiment and co-simulation of Carsim and Simulink.
