Abstract
A system and method implements improved machine performance, most preferably for gas turbine engines. The system and method implement a control law that receives sensed operational parameter feedback signals. For each sensed engine operational parameter, the feedback signals that are supplied to the control law selectively comprise the sensor signal representative of the engine operational parameter, if the sensor signal is valid, or an observer estimate of the sensed engine operational parameter, if the sensor signal is invalid.
