Tiltrotor Aircraft SCAS Design Using Neural Networks [PDF]
Journal of Control, Automation and Systems Engineering, 2005 This paper presents the design and evaluation of a tiltrotor attitude controller. The implemented response type of the command augumentation system is Attitude Command Attitude Hold. The controller architecture can alleviate the need for extensive gain scheduling and thus has the potential to reduce development time.

Time-varying linear control for tiltrotor aircraft
Chinese Journal of Aeronautics, 2018 Abstract Tiltrotor aircraft have three flight modes: helicopter mode, airplane mode, and transition mode. A tiltrotor has characteristics of highly nonlinear, time-varying flight dynamics and inertial/control couplings in its transition mode. It can transit from the helicopter mode to the airplane mode by tilting its nacelles, and an effective ...
