A data-driven approach to real-time controller reconfiguration for fault tolerance

In this paper, we formulate the fault-tolerant control (FTC) problem in the behavioral system theoretic framework. To solve this problem, two methodologies are presented, which rest under the broad classification of FTC systems, namely projection-based approach and online redesign approach. The novelty within these approaches lies in the fact that any a priori information about the plant is not available in real-time. In addition, no online identification or estimation of the running plant is carried out. Rather, the real-time fault accommodation is solely based on the online measurements generated by the unknown plant.
