초록

A dual fault tolerant control system for controlling power delivered to an actuator from a power source includes decoders which accept commands representing the length of time power is to be applied to the actuator. Controllers process the command and control power inhibits based upon the length of time indicated by the command for supplying power to the actuator. The dual fault tolerant feature allows reassurance that power is applied to the actuator for the length of time dictated by the command.
