摘要/Abstract

摘要： 针对信息物理系统的安全控制问题,提出拒绝服务攻击下基于事件触发的保性能控制方法.首先,考虑到拒绝服务攻击行为的随机特性,将拒绝服务攻击描述为具有固定丢包数的伯努利随机分布过程;其次,为了降低网络通信负担,采用离散事件触发通信机制对传感器的量测信息进行传输;随后,根据Lyapunov稳定性理论和线性矩阵不等式方法给出拒绝服务攻击下系统稳定的充分条件,进而在给定的保性能水平下设计了基于事件触发机制的保性能控制器;最后,通过仿真实例验证了所提出控制方法的正确性和有效性.

Abstract: An event-triggered guaranteed cost control method is proposed for security control problem of cyber-physical systems (CPS) under denial of service(DoS) attacks. Firstly, the effect of DoS attacks is described as a Bernoulli random distribution process with the fixed number of packet losses by considering the characteristic of DoS attacks. Secondly, in order to reduce the network communication burden, the discrete event-triggered communication mechanism is used to transmit the measured information of the sensors.Then, according to Lyapunov stability theory and linear matrix inequality method, the sufficient conditions for system stability under denial of service attack are given, and then a guaranteed cost controller based on event triggering mechanism is designed at a given guaranteed cost level. Finally, the correctness and effectiveness of the proposed control method are verified by a simulation example.

Key words: cyber-physical systems, denial of service attack, event-triggered, guaranteed cost control
