         10 . A method in accordance with  claim 7 , wherein the method further comprises providing a null bias integration to the control loop. 
     
     
         11 . A method in accordance with  claim 7 , wherein the method further comprises providing adjustable gains to the control loop. 
     
     
         12 . A method in accordance with  claim 7 , wherein the method further comprises executing a health and status check of the component from instructions stored in local non-volatile memory. 
     
     
         13 . One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by a controller, the computer-executable instructions cause the controller to:
 receive, by a component of a gas turbine engine, commands for a hardware module of the component;   process, by the component, the received commands for the hardware module; and   queue, by the component, the received commands in an input buffer; and wherein the method further comprises storing failure commands within the input buffer.   
     
     
         14 . One or more non-transitory computer-readable storage media according to  claim 13 , wherein the computer-executable instructions cause the controller to store failure commands within the input buffer. 
     
     
         15 . One or more non-transitory computer-readable storage media according to  claim 14 , wherein the computer-executable instructions cause the controller to execute failure commands upon the loss of received commands in the input buffer. 
     
     
         16 . One or more non-transitory computer-readable storage media according to  claim 14 , wherein the computer-executable instructions cause the controller to provide lead/lag compensation to the received commands.
