Abstract

In this paper, a conceptual overview of the Integrated version of Fault-Tolerant Control is presented. When dealing with uncertainty, the interconnected design needs an integrated approach to make a balance between performance and robustness. Indeed the integrated approach is very significant for the design and development of fault-tolerant control schemes. In this paper, the Integrated Fault-Tolerant Control (IFTC) approaches are investigated in two FDI-based IFTC and FE-based IFTC classes depending on the applications of either Fault Estimation (FE) or Fault Detection and Isolation (FDI) techniques. These two classes are delicately distinguished and reviewed from the integration strategy’s perspective and according to the design methodology criteria. A comparison of these categories is concisely conducted. The integration is manifested in the coupling of FE and FTC, and the synthesis of the FDI unit. Moreover, the history of “integration” theory including its development process according to today’s industry requirements, and its successful consequences that have been noticed in recent years are presented to make an overall vision in this area.
