Fault diagnosis on a magnetically supported plate

摘要

A model-based online fault-diagnosis scheme for an electromagnetically supported plate is presented as an example of a nonlinear and open-loop unstable system. First, residuals for sensor as well as for actuator faults are generated using algebraic derivative estimators. Then, the robust detection and isolation of step-like sensor and actuator faults is presented. The performance of the proposed algorithms is illustrated by experimental results.
