Sensor attack detection for cyber-physical systems based on frequency domain partition

摘要

This study is concerned with the attack detection (AD) problems in finite frequency domain for cyber-physical systems with sensor attack. The frequency domain is divided into three frequency domains of low, medium and high, multiple AD filters are designed to work simultaneously. The attack detectionAD problem is transformed into a multi-objective optimisation schemes for each finite frequency domain. Finally, the experimental results of networked motion control system are given to verify the effectiveness and superiority of proposed method.
