SYSTEMS AND METHODS FOR COMMANDED OR UNCOMMANDED CHANNEL SWITCHOVER IN A MULTIPLE PROCESSOR CONTROLLER

Abstract:

Methods and systems for electronic engine control (EEC) systems are disclosed. An EEC monitors and controls operation of an end effector, such as a torque motor. The EEC is configured to command a switchover from an active channel to a standby channel, or vice versa, in response to a trigger (e.g., a command or a fault). The switchover is executed automatically upon identification of the trigger due to the detection of a fault without the need of a command, over a predetermined time or number of cycles within a command signal.
