Fault Detection, Estimation/Reconstruction, and Fault-Tolerant Control: Theory and Practice

The increasing complexity of modern engineering systems will correspondingly increase the possibility of system faults and/or failures. The occurrence of sensor, actuator, and/or component failures may dramatically degrade system performance and even result in catastrophic system collapse. As a response to high requirement for system safety, reliability, and survivability, fault diagnosis and fault-tolerant control (FTC) for dynamic systems have been attractive subjects of many investigations in control community and have received considerable attention during the past few decades, and a great deal of research progress has been made. The articles in this special issue speak on recent development of fault detection, estimation/reconstruction, and faulttolerant control as well as their applications. The following sections briefly explain the outcome of published articles in this special issue.They are divided into five key research areas based on publications.
