Abstract
Taking the two-dimensional airfoil section model with two degrees of freedom as the object, this paper develops a multi-parameter optimization method, which regards the minimum system response under the given gust disturbances as the objective function and gives the expression describing the state space form of response sensitivity in which the matrix parameter sensitivity solution obtained by CVD method, further more, the Newton iteration method based on the sensitivity is adopted to realize the parameter optimization. By the simulated calculation of numerical examples and comparing with the conventional method, the optimization method has the advantage of better calculation efficiency and robustness and being used for aircraft design.
