| 摘 要： | 首先从研究倾转旋翼机的全量非线性飞行动力学模型入手,建立倾转旋翼机的非线性仿真模型,并提取其全包线飞行的配平模型;其次利用模糊缝合技术实现由有限线性配平模型拟合非线性模型,从而可以得到具有实时计算能力的近似非线性模型;最后通过对比缝合模型与非线性模型的操纵响应结果可知,二者具有良好的一致性,所建模型有效地提高了计算效率...

| Abstract: | Firstly,in this paper the full nonlinear flight dynamical mathematical model of a tilt rotor aircraft was analysed and the nonlinear flight simulation model was established.The full envelope trim models were obtained by simulation.Secondly,the real time approximate nonlinear model was got by using the limited trim points linear model with the model fuzzy fusion methed.Finally,the responses about the fusion model and the nonlinear model were practical unanimity by relative analysis,which could refrain from c... |
