| Summary: | Rotor systems used in modem aircraft engines are subject to damage when anomalies arise due to extended normal operation or extreme operating conditions. The incorporation of electromagnetic bearings in these engines facilitates the use of an expert system for detection of the anomalies and for temporary corrective action via the bearing controller. The present study investigates the use of a fuzzy logic based expert system on a personal computer for on-line anomaly detection and corrective action. The expert system is evaluated on a test rotor with an electromagnetic bearing controlled by a digital signal processor. The current research extends previous rotor expert systems by incorporating corrective action by directly affecting bearing controller parameters. Also novel is the use of a fuzzy logic expert system in the LabVIEW programming environment for a rotor system. |
