报告内容:Recent advances in information and communication technologies, embedded systems and sensor networks have generated significant research activity in the development of cyber-physical systems, where a large amount of sensor data is collected and processed in real-time in order to achieve smooth and efficient operation of the underlying system. The current trend is towards larger and larger sensor data sets, leading to so called big data environments. However, in situations where faults arise in one or more of the sensing devices, this may lead to a serious degradation in performance or even to an overall system failure, especially as a result of propagating faults in interconnected subsystems. The goal of this presentation is to motivate the need for fault diagnosis in cyber-physical systems and to provide a methodology for detecting and isolating multiple sensor faults in a class of nonlinear dynamical systems. The detection of faults in sensor groups is conducted using robust analytical redundancy relations, formulated by structured residuals and adaptive thresholds. Various estimation and learning algorithms will be presented and illustrated, and directions for future research will be discussed.
