Abstract:

In this paper, sensitivity approaches are taken to analyse and design an integrated flight/propulsion control system where the interaction between subsystems directly affects the stability property and handling performances of the aircraft. The eigenvalue sensitivity approach is employed to study the effect of coupling parameters on system stability and gain sensitivity approach is used to direct the reduced states feedback sub-optimal control system design. Simulation results shew that the integrated flight/propulsion control system designed by sensitivity approaches is of good performance.

Key words: integrated control systems, flight control, propulsion control, eigenvalue sensitivity, gain sensitivity
