This paper deals with the problems of the optimal control of the airplane landing in presence of atmospheric turbulence with application of the theory and me-thods of random optimal control. By use of covariance analysis technique a propagation equation of the error variances of linear discrete random system is derived which allows to calculate directly the airplane landing precision. And the influence of filtering sensitivity on the airplane landing control is further analysed.

In China, There occur sometimes overshoot and oscillation during aircraft landing. We propose a twoinputtwooutput fuzzy nonlinear control system to alleviate the undesirable effects of such occurrence. The main problem is the overshoot of height of flight and a secondary problem is the velocity oscillation. We employ two controllers to deal with these two problems which are to some degree coupled. We give the fuzzy control rules and tables concerning the height and velocity of a type of aircraft. We propose...

In China, There occur sometimes overshoot and oscillation during aircraft landing. We propose a twoinputtwooutput fuzzy nonlinear control system to alleviate the undesirable effects of such occurrence. The main problem is the overshoot of height of flight and a secondary problem is the velocity oscillation. We employ two controllers to deal with these two problems which are to some degree coupled. We give the fuzzy control rules and tables concerning the height and velocity of a type of aircraft. We propose a special method for decoupling the height overshoot and velocity oscillation problems in this nonlinear system. Simulation results(Figs.2 and 3) indicate that our proposed method is effective in reducing height overshoot and velocity oscillation.

This paper is concerned with the problem of airplane landing under the influence of wind disturbance. By combining the H ∞ optimization method with the structural perturbation approach of large scale systems, a hierarchical H ∞ controller is developed to guarantee the robust stability of the system. Since the system matrix is not invertible, a new method is suggested to get the perturbation matrix. The application to flight control shows that the influence of wind disturbance can be restrained by using the...
