| 摘 要： | 建立了非线性非定常气动力的模糊逻辑模型。利用大迎角俯仰及滚转振荡气动力验证了模型的有效性。结果表明：该模糊逻辑模型对非定常气动力有很好的预测能力；利用模糊逻辑方法可建立包括非基本运动状态变量在内的多变量非线性非定常气动力的数学模型。

| Abstract: | A fuzzy logic modeling of nonlinear unsteady aerodynamics is developed in this paper. Aerodynamic data for a model obtained in forced pitching and rolling oscillation at high angles of attack has been used to verify the modeling. The results show that it predicts the unsteady aerodynamics very well. This method can be used to develop models with multiple variables including non-basic flight variables. |
