地效翼船自控参数的优化研究(英文)

Study on Optimization of Automatic Control Parameters for WIG Ship

介绍了基于地效翼船空间运动方程的自控参数优化方法。首先建立了带有自控参数的地效翼船空间运动方程;再以MATLAB为工作平台,利用其非线性多目标函数fmincon(),建立优化系统的数学模型;最后采用MATLAB/GUIDE编制了自控参数优化程序,对地效翼船自控参数进行了优化计算。结果表明:通过地效翼船自控参数的优化计算,可以达到规定的运动性能指标,不必单纯依靠气动设计来解决地效翼船的运动稳定性和操纵性问题。

A method based on the space motion equation of Wing-In-Ground-Effect Ship （WIG Ship） for optimization of automatic control parameters is introduced. First, the space motion equation of 〈WIG Ship＋Automatic Control System〉 is established. And then MATLAB is chosen as the main software support for establishing the mathematical model of optimization system with the help of its nonlinear multivariable function fmincon （ ）.Finally,the optimum procedure of automatic control parameters is programmed on the platform MATLAB/GUIDE,and the optimization calculation of automatic control parameters can be carried out. The results show that,through optimized calculation of automatic control parameters of WIG Ship,optimal results may be achieved,and for solving the questions of the dynamic stability and maneuverability of WIG Ship,it is unnecessary purely to depend on the aerodynamic design only.
