N2 - This paper investigates the preview-based altitude control of a very flexible flying wing model. The preview control system employs a two-loop control scheme, which is designed based on the reduced-order linear model. The outer loop employs PI/LADRC (linear active disturbance rejection control) algorithms to track the altitude reference command and generate pitch angle command to the inner loop, based on which the inner loop uses mathbf{H}-{infty} preview control to compute the control inputs to the corresponding control effectors. A Lidar (light detection and ranging) simulator is developed to measure the wind disturbances at a distance in front of the aircraft, which are provided to the inner-loop mathbf{H}-{infty} preview controller as prior knowledge to improve control performance. Simulation tests are conducted based on the full-order nonlinear model, which show that the preview-based altitude control system achieves better tracking effectiveness and disturbance rejection performance than the baseline non-preview control system.
