To handle more complex dynamic behavior due to high-aspect-ratio wings in very flexible aircraft, more complex models and control methods are needed. In this paper, a control approach is proposed which combines a loop-separation architecture with inner and outer loops and a reference governor that acts as a safety supervisor for reference inputs to the autopilot. While the inner-loop is capable of controlling the shape of the aircraft and providing stability, the outer-loop ensures tracking of velocity, altitude, bank and heading angles. The reference governor complements this architecture and protects the system against constraint violations. The modularity of this approach facilitates the practical implementation of this control architecture.
