摘要
为了更好地完成着陆任务,引入自适应模糊控制算法应用于飞机自动着陆时下降以及改平的纵向控制中,利用变论域收缩因子来优化模糊控制器的量化因子,同时配合模糊规则对比例因子的自适应调整,从而使飞机更精确地跟踪下滑道。通过仿真表明该控制系统具有良好的动态性能,有效地提高了飞机自动着陆的精度。
In order to finish the landing task well, control algorithm of adaptive fuzzy was introduced to control the decline and flare of longitude. The shrinkage factor of variable universe was used to optimize the quantifying factor of fuzzy controller, and the scale factor was adjusted adaptively by fuzzy rules, so the airplane can track glide slope accurately. It is proved that the adaptive fuzzy control system has good dynamic performance and improves the automatic landing precision.
