AB - © 2017 American Automatic Control Council (AACC). This paper investigates the trajectory control of a very flexible flying wing model, which is derived from geometrically-nonlinear beam theory using intrinsic structural description in [1]. This model is coupled with structural dynamics, aeroelastic dynamics and flight dynamics. The control design is using a two-loop LADRC (linear active disturbance rejection control) and H ∞ scheme in both the longitudinal and lateral channels, based on a reduced-order linearised model. In each channel, the outer loop (position control) employs LADRC technique to track desired flight routes and generate attitude command to the inner loop, while the inner loop (attitude control) uses H ∞ control technique to track the attitude command generated from the outer loop and computes the control inputs to the corresponding control surfaces. The simulation tests are conducted in a reduced-order nonlinear model (the reduced-order linearised model with a quadratic nonlinear term). Simulation study shows that the trajectory control system achieves good robust and tracking performance. We mention that the simulation differences between the reduced-order and full-order nonlinear models are negligible in the case of trajectory control tests.
