Abstract

The signal selection and signal consolidation appts. is for use with the redundant sensor signals in a triply redundant control system. One of the redundant sensors supplies precise information and the remaining two sensors supply less precise information. Signal selection is based on the operational state of the three sensors, with the signal provided by the precision sensor being selected whenever the precision sensor is operational. If the precision sensor fails, each channel is supplied with a signal that is a weighted average of the signals supplied by the two less accurate sensors.
