Fault-tolerant control systems

WebApr 9, 2024 · The concept of fault-tolerant control has extensively been explored with various mapping of development. It starts from the system characteristic, the robustness of the controller, estimation methods and optimization, to the combination of the faults such that it can touch the true observed system. The mathematical concepts of the scrubber … Webfew decades on developing mechanisms for obtaining fault-tolerance in different types of systems. These range from conceptually simple modular redundancy schemes to more advanced model-based fault-diagnosis techniques. The need for a rigorous theory of secu-rity in control systems has only recently been recognized as a fertile and important area

WebJul 1, 2024 · Fault-tolerant control is a control strategy that can keep the closed-loop system stable when sensors, actuators, or components fail and meet specific performance requirements, making the system’s feedback insensitive to faults. Fault-tolerant control (FTC) can generally be divided into passive and active methods. Web20 languages. Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of one or more faults within some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system, in which even a ...
