摘要
Abstract
Several unsteady aerodynamics mathematic models are modeled with account of fighter pitching maneu ver including polynomial model, Fourier analysis model, state space model, difference equation model and fuzzy logic model. The model parameters are identified by wind tunnel test data of SDM. In the end of paper, it gives the differ ences about the mathematic models in the way of physical significance, applicability, precision and so on.关键词
