摘　　要：为了实现直升机自动过渡悬停功能,首先运用模糊建模方法建立全包线飞机特性的T-S模型;然后基于增稳控制系统,实现飞机姿态角的稳定;在此基础上引入"多普勒"地速与无线电高度信号,设计高度和速度控制器,使飞机实际输出跟踪指令信号;最后提出了两种合理的高度速度指令设计方案,使得飞机能快速平稳地悬停到预定高度。仿真结果表明,该设计方法有效可行。In order to achieve the automatic transition and hovering capability for helicopter, the helicopter large scale flight envelop T-S model is built with the fuzzy modeling. The stability of attitude angles is realized based on the stability augmentation control system. The Doppler ground-speed and radio altitude signals are introduced to design the altitude and speed controller, which make the actual output track the command signal. Lastly, the two rational schemes of altitude and velocity command are designed reasonably to make the helicopter quickly and smoothly realize the function of transition and hovering. A numerical simulation shows that the design approach is available and effective, and some conclusions are proposed.
