| 摘 要： | 提出了一种基于集员辨识理论的直升机全耦合飞行动力学模型参数辨识方法.该方法针对直升机飞行动力学模型耦合强,难以得到辨识模型和待辨识参数之间显式函数关系的特点,推导并建立了状态空间微分方程形式模型集员辨识的间接辨识算法.通过引入广义噪声的概念以及对其边界的灵活设定,实现了对辨识参数众多、耦合严重且灵敏度差异大的复杂模型的...

| Abstract: | A method based on the set-membership identification theory for the parameter identification of a helicopter fully coupled flight dynamics model is presented.In view of the fact that the helicopter flight dynamics model is seriously coupled and that it is difficult to obtain explicit function relationships between the identification model and the parameters to be identified,an indirect identification algorithm is created in this method for the set-membership identification in the form of a state-space differ... |
