Fuzzy logic model of nonlinear uns teady aerodynamics with multiple variables

摘要: 应用模糊逻辑算法，建立了带升降舵偏角影响的非线性非定常气动力模糊逻辑模型，并进行了验证。结果表明：所建立的非定常气动力模糊逻辑模型有较强的预测能力。此方法为今后建立多变量、复杂运动的非线性非定常气动力数学模型，提供很好的借鉴。

Abstract: A fuzzy logic model of nonlinear unsteady aerodynamics with theelevator deflection angle is developed,using a fuzzy logic algorithm.The model is proved by large-amplitude pitch-up oscillation test data.The results show that the developed model has a good
