Computer Aided Optimal Recovery from Windshear

The principles of the computer aided direct optimization of dynamic system are introduced here,and as a real example,the method is applied to the aircraft recovery from low altitude windshear.After using a real engineering windshear model and choosing a proper structure of control function,a satisfactory performance function and its reasonable restrains,the control of aircraft recovery from low altitude windshear is optimized,by the computer researching for the optimal condition directly,systematically and alternatively.Curves of parameters in the flight corresponding to the optimal recovery are obtained,as well as the comparison of the results with those from the un optimized recovery guiding policy.The final results show that the performance of recovery is greatly improved after the optimization.
