A Survey of Decentralized Fault-Tolerant Control Systems

As technology has progressed, the demand for a system's reliability and safety under potential faults is an essential issue. Fault-tolerant control systems strive to handle failures of the system components and preserve stability while reducing performance degradation to a tolerable degree. Therefore, fault-tolerant control systems become an urgent necessity, especially for large-scale systems, due to their complexity, which raises the possibility of malfunctions. The main contribution of this paper is to present a comprehensive review of decentralized fault-tolerant control for large-scale systems, including the latest techniques in this field. Several strategies were compared based on the development of decentralized fault-tolerant control techniques used to address the impact of faults on such systems
