摘要: 综合考虑气动导数建立了无人战斗机非线性模型,从配平的实质出发设计了一个代价函数,将非线性系统的配平问题转换成求代价函数最小值的问题,通过求最小值算法求出无人战斗机的配平点。以直线平飞为算例验证了配平方法的有效性,最后通过对纵向模态的分析说明了无人战斗机模型的合理性。

Abstract: In this dissertation, a nonlinear numerical model of UCAV is established. To establish the model, all Aerodynamic derivatives are considered. From the Substance of the UCAV trim, a cost function is designed. So the problem of nonlinear system trimming converts to seek the minimum of the cost function.The minimum algorithm colculation derived the UCAV trim point. An example of level flight is to show the effectiveness of the trim method. Finally, through the analysis of the longitudinal mode shows the UCAV model is reasonable.
Key words: UCAV; nonlinear model; trim; cost function
