| Abstract: | Application of the quantitative feedback theory( QFT) to the design of a longitudinal pith-axis flight control system for an elastic aircraft with uncertainty in the dynamic model is presented, the disturbance is also considered. The simulation results indicate that the controller designed using QFT has good robustness and gives a structural mode damping improvement. It is demonstrated that QFT is an effective method for the controller design of the elastic aircraft. |
