Case study on behavioral approach to fault-tolerant control: Application to an electric circuit

摘要

In this paper, we present a case study for fault-tolerant control of an electric circuit in the behavioral framework. First, we demonstrate the modeling of electric circuit using the behavioral point of view, where no a priori input-output partition has been made. The uniqueness of behavioral approach lies in the fact that it deals only with variables describing the system without any dedicated (external or internal-type) representation. Taking this point of view, we present a novel real-time fault-tolerant control strategy, which does not require an explicit model-based fault diagnosis unit. Instead, the controller is reconfigured online directly based on the system trajectories, and the given control specifications. In this way, we inherently excrete the shortcomings that are often seen in model-based fault-tolerant systems.
