“…One of the advantages of the above switching strategy is that the only information that is required for controller reconfiguration is the knowledge of the fault occurrence, which can be determined through a large body of fault detection algorithms that are available in the literature (refer to recent work in [23,22,35] and the references therein). The proposed reconfigurable approach does not rely and require exact knowledge of the severity of a fault (fault identification) as long as Assumption 3 parts (b) and (c) are satisfied.…”

“…Nevertheless, improved results were developed for avoiding complexity by either applying integer linear programming to Petri nets [123] or using partially observed Petri nets [124]. Recently, event-based approaches were applied to fault isolations for continuous dynamic processes where a high-level discrete-event system fault diagnoser was employed to improve the robustness of the fault diagnosis against large environment disturbances [125] or isolate abrupt parameter faults [126].…”

IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS Abstract-With the ever increase of complexity and expense of industrial systems, there is less tolerance for performance degradation, productivity decrease and safety hazards, which greatly stimulates to detect and identify any kinds of potential abnormalities and faults as early as possible, and implement realtime fault-tolerant operation for minimizing performance degradation and avoiding dangerous situations. During the last four decades, fruitful results were reported about fault diagnosis and fault-tolerant control methods and their applications in a variety of engineering systems. The three-part survey paper aims to give a comprehensive review for real-time fault diagnosis and fault tolerant control with particular attention on the results reported in the last decade. In the first-part review, fault diagnosis approaches and their applications are reviewed comprehensively from model-based and signal-based perspectives, respectively.

“…The FDI modules use conventional fault diagnosis techniques such as those that are proposed by one of the authors in [34][35][36] where detection filters are designed based on 'differential geometry' techniques. By using inputs and outputs of the system, these detection filters are shown to be able to detect and isolate faults in a network of unmanned vehicles.…”

In this study, the problem of cooperative fault accommodation in formation flight of unmanned vehicles represented by linear time-invariant models that are subject to loss-of-effectiveness actuator faults is investigated through a hierarchical framework. Three hierarchical levels are envisaged, namely a low-level fault recovery (LLFR), a formation-level fault recovery and a high-level supervisor. In the LLFR module, a recovery controller is designed by using an estimate of the actuator fault. A performance monitoring module is then introduced at the high-level to identify a 'partially low-level recovered' vehicle because of inaccuracy in the fault severity estimate that results in violating the 'error specification' of the formation mission. The high-level supervisor then activates the formation-level fault recovery module to compensate for the resulting performance degradations of the partially low-level (LL) recovered vehicle at the expense of other healthy vehicles. The fault is accommodated by reconfiguring the formation structure through the novel notion of the weighted absolute measurement formation digraph, activating a robust controller for the partially LL recovered vehicle, and imposing a constraint on the desired input signals. Numerical simulations for a formation flight of five satellites in the planetary orbital environment are presented to confirm the validity and effectiveness of the proposed analytical work.
