SYSTEM AND METHOD FOR MODEL-BASED SENSOR FAULT DETECTION AND ISOLATION

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable system relating to model-based sensor failure detection and isolation for an engine.;SOLUTION: The system and method may include steps of: receiving a plurality of measured tuning inputs 114 associated with an operating parameter of an engine 104; providing a plurality of parameter estimation modules that utilize one or more component performance maps having adjustable knobs to generate model outputs; calculating residual values for each parameter estimation module; adjusting knobs of each parameter estimation module; and determining that a sensor 108 associated with a measured tuning input 114 or a fundamental input 116, 112 is faulty based on at least in part on values of the knobs and residual values.;COPYRIGHT: (C)2009,JPO&INPIT
