A Sensor Failure Detection 'Scheme Using Analytical Redundancy And U-D Filtering Algorithm For LCA.

摘要

This Report Documents The Performance Of A Sensor Failure.udDetection Scheme Based On Duplex Hardware-Analytical Redundancy . The Absolute Residuals And Accumulated Residuals, From• U-D Factorization Filtering Algorithm Which Monitors The Performance Of The Closed Loop System Of An Aircraft, Are Used For Detection And Switching Purpose When Bias And Drift Type Sensor' Failures Occur.ud
