Abstract
A method for managing mismatches in feedback from guide vane sensors of a turbine engine with variable guide vanes includes selectively muting individual feedback channels and obtaining time series turbine performance data of the turbine engine associated with individual feedback channels. The feedback channel of the guide vane sensor associated with the best performing time series performance data can be selected as sole feedback channel following detection of a mismatch condition.
