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.
What is claimed is: 1. A control system for a gas turbine engine including a plurality of actuators, the system comprising: an engine control law adapted to receive input commands and a plurality of feedback signals, each feedback signal representative of a sensed engine operational parameter, the engine control operable, in response to the input commands and the plurality of feedback signals, to supply engine actuator commands; a gas turbine engine observer adapted to receive the engine actuator commands and a plurality of sensor signals, each sensor s...
