The lateral directional channel decoupling is reached through eigenvector shaping. And then the trajectory programming for lateral maneuver types is presented. On these bases, the ‘pilot helicopter’ closed loop system is formed, and the simulation results under different maneuvers, such as snaking, of the helicopter with lateral directional SCAS are satisfactory.

文摘In this paper, the eigenstructure assignment theory and methods are applied to design the lateral directional channel of armed helicopter SCAS (Stability and Control Augmentation System). The lateral directional channel decoupling is reached through eigenvector shaping. And then the trajectory programming for lateral maneuver types is presented. On these bases, the ‘pilot helicopter’ closed loop system is formed, and the simulation results under different maneuvers, such as snaking, of the helicopter with lateral directional SCAS are satisfactory. The results of design are valuable for practical engineering.
