Special Issue Information

Dear Colleagues,

The complex system has too many components that are highly interconnected with each other. The human brain is one of the most beautiful examples of complex systems and infrastructure, such as power grids, transportation systems, ecosystems, and so on. In complex systems, if one fault occurs, it can cause the entire system to fail, or it will give very poor performance during normal operations. In this situation, the control systems play an important role in ensuring the reliability, safety, and efficiency of these systems. With the development of science and technology, modern control systems have become more and more complicated. Roughly speaking, the normal operation of the control systems depends on the normal operation of many internal components. However, due to the increasing complexity of internal components, modern control systems face the risk of internal component failure and communication failure, resulting in the system not working normally. Therefore, fault-tolerant control mechanisms and fault diagnosis methods play important roles in ensuring that complex systems work regularly.

This Special Issue focuses on fault-tolerant control mechanisms and fault diagnosis methods for complex systems. Topics of interest include, but are not limited to, the following:

  • Fault-tolerant control for complex networks against sensor and actuator failure;
  • Fault diagnosis for complex dynamical networks;
  • Fault diagnosis and fault-tolerant control for multi-mode systems;
  • Fault-tolerant control for complex cyber-physical systems;
  • Fault diagnosis for fuzzy systems;
  • Learning-based fault-tolerant control mechanisms and fault diagnosis methods;
  • Data-driven approaches for the fault-tolerant control problem.

Abstracting causal knowledge from process measurements has become an appealing topic for decades, especially for fault root cause analysis (RCA) based on signals recorded by multiple sensors in a complex system. Although many causality detection methods have been developed and applied in different fields, some research communities may have an idiosyncratic implementation of their preferred methods, with limited accessibility to the wider community. Targeting interested experimental researchers and engineers, this paper provides a comprehensive comparison of data-based causality detection methods in root cause diagnosis across two distinct domains. We provide a possible taxonomy of those methods followed by descriptions of the main motivations of those concepts. Of the two cases we investigated, one is a root cause diagnosis of plant-wide oscillations in an industrial process, while the other is the localization of the epileptogenic focus in a human brain network where the connectivity pattern is transient and even more complex. Considering the differences in various causality detection methods, we designed several sets of experiments so that for each case, a total of 11 methods could be appropriately compared under a unified and reasonable evaluation framework. In each case, these methods were implemented separately and in a standard way to infer causal interactions among multiple variables to thus establish the causal network for RCA. From the cross-domain investigation, several findings are presented along with insights into them, including an interpretative pitfall that warrants caution. Full article
