Automatic calibration of redundant sensors

A system for calibrating the sensors of a redundant sensor system by calculating a first set of error signals based on differences between a combination of the outputs and known values and calculating a second set of error signals based on differences between the parity among preselected sensors and...

Zusammenfassung:	A system for calibrating the sensors of a redundant sensor system by calculating a first set of error signals based on differences between a combination of the outputs and known values and calculating a second set of error signals based on differences between the parity among preselected sensors and a predetermined value and calculating, from the first and second set of error signals, a plurality of calibration signals to be added to the output of the individual sensors which are in error so as to correct their outputs.
