ABSTRACT:
A flight control system that provides energy management for an aircraft. The flight control system includes an energy control system which generates a first error signal that is a function of an actual energy characteristic and a threshold energy characteristic. The energy characteristic may be the bleed rate of the aircraft. The error signal is converted into a control surface command signal which moves the control surface(s) of the aircraft, accordingly. The control system limits the movement of the control surface(s) so that the actual energy characteristic does not exceed the threshold energy characteristic. The energy control system can be coupled to a nominal control system which generates a second error signal that is a function of a pilot input command and a feedback signal which is indicative of the present state of the aircraft. The second error signal can also be converted to a control surface command signal which moves the control surface(s) of the aircraft. The flight control system can contain a select element which converts the first error signal into the control surface command when the second error signal is less than the first error signal, or converts the second error signal into the control surface command when the second error signal is not less than the first error signal.
