and one or more monitoring devices such as sensors 106 for monitoring one or more parameters of the engine 10 the sensors 106 may be any sensor suitable for monitoring the engine parameters examples of such sensors 106 include but are not limited to speed sensors pressure sensors temperature sensors humidity sensors and accelerometers the conditioning unit 102 may comprise a digital computer or processor unit for conditioning noisy signals as will be discussed further below the control unit 104 may comprise a digital computer or engine control unit ecu not shown in communication with the hardware of the engine 10 for controlling an operation of the latter in particular the conditioning unit 102 and the control unit 104 may be part of a full authority digital engine control fadec not shown used to manage operation of the gas turbine engine 10 by controlling the engine 10 through acceleration deceleration and steady state operation the fadec may modulate fuel flow to the engine 10 schedule and control surge protection systems protect the gas turbine engine 10 from overspeed and overtemperature perform complete engine start control as well as control opening and closing of bleed off valves and other engine variable geometries the sensors 106 illustratively monitor responses of one or more engine components identify the health of these components and deliver an output as required in particular the sensors 106 sense one or more engine parameters and generate sensed signal s accordingly the rate of change in the one or more engine parameters may then be monitored by computing a derivative of.
