Abstract :
An H∞ method for propulsion controlled aircraft (PCA) design is introduced. The PCA system is adopted for emergency fly-by-throttle control of an airplane with multiple control surface failure. The H∞ methodology is applied to the problem of matching by dynamic compensation the throttle-actuated crippled aircraft and the nominal control-surface-actuated aircraft model. The design procedure is used to synthesize model matching H∞ controllers for an L-1011, a commuter airliner, and a thrust vectoring aircraft model in longitudinal motion and an L-1011 model in lateral motion. Simulation results demonstrate that the concept is workable
