Abstract: Apparatus for signal selection and signal consolidation of the redundant sensor signals in a triply redundant control system wherein one of the redundant sensors supplies precise information and the remaining two sensors supply less precise information is disclosed. 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. In some arrangements of the invention whenever the precision sensor has not failed, but supplies a signal that deviates substantially from the signals being supplied by the two less accurate sensors, the signal supplied to each channel of the control system is a weighted average of all three sensor signals.
