一种采用新型抑制函数的地形跟随控制技术

A Terrain Following Technology with New Stay Function

提出了一种采用新型抑制函数的地形跟随控制技术,并以某电传操纵飞机为例,设计了航迹倾角(γ)控制律,同时通过地形跟随六自由度仿真计算,比较了不同抑制函数对地形跟随性能的影响。仿真结果表明,采用该新型抑制函数后,飞机的地形跟随飞行性能得到了大大提高。

A terrain following technology with a new stay function was introduced in this paper. One fly-by-wire aircraft was used as an example. At first, its climbing track angle （γ） control law was designed. Then a six-degree-of-freedom nonlinear simulation was performed with several kinds of stay function. And the result shows that the new stay function can greatly improve the quality of the TF（terrain following） flying.
