Fault tolerant control and fault detection/isolation design for linear parameter varying systems

摘要

Fault tolerance is vital to ensuring the integrity and availability of safety critical systems. Fault tolerance encompasses all of the architecture design and algorithms required to guarantee proper system operation during both normal and failure conditions. A fault tolerant system must include the logic and algorithms for fault detection, isolation, and reconfiguration to continue operation in the face of faults or failures. The main objective of the fault detection and isolation research area is to study and develop methodologies for identifying and exactly characterizing possible incipient faults arising in predetermined parts of the plant. The natural step after diagnosis is the design of a controller to tolerate the fault effect, fault tolerant control, to guarantee pre-specified performance of the faulted system.
