Networked-Based Fixed-Time Discontinuous Safety Control for DDW Systems Under Stochastic Cyber-Attacks and Intermittent DoS Attacks

This study investigates the network-based fixed-time stabilization problem of the direct drive wheel (DDW) system of electric vehicles under stochastic cyber-attacks and intermittent denial of service (DoS) attacks via reliable discontinuous control strategy, which has important research significance for the application of the communication network security of the direct drive wheel system of electric vehicles. Firstly, aiming at the fact that the widths of control channels induced by stochastic cyber-attacks are inconsistent, a new controller based on quantization discontinuous delay control method is designed. Secondly, the actuator fault is also taken into account to conform to the actual operation of the direct drive wheel system of electric vehicles. Moreover, given the reliability of controllers in practical engineering, this work develops a new sufficient condition for easy implementation based on Lyapunov functional, and construct a new reliable discontinuous safety controller with stochastic cyber-attacks and intermittent DoS attacks to control the stability of the direct drive wheel system of electric vehicles in fixed time. Finally, the correctness and feasibility of the developed theoretical results are verified by experiments.
