μ synthesis control technique is used to develop controllers of longitudinally automatic landing systems for a commercial airplane. The controller provides decoupled tracking of altitude and speed, disturbance rejection to wind. The system has to be robust against uncertainty of system. Based on formulation problem and system design specification, a open loop synthesis architecture is defined and the related weighting functions are chosen. A feedback controller is obtained from optimization via DK iteration. A large commercial aircraft is employed to illustrate the potential of the method. Simulations show that the glide slope capture motion and a flare maneuver are accomplished quite well. And the controller has dynamic performance, the imposed robustness and rubust performance.
