| 中文摘要 |
| 垂直/短距起降飞机是一类典型的非最小相位系统. 系统的负调特性使得飞机高度响应比较缓慢, 并且会在初始阶段响应为负, 从而出现不期望的掉高现象. 针对该问题, 本文设计了新的最小相位预估控制器, 通过调节近似输出零点的方法提高系统的动态响应; 对于负调部分, 采用两步参数整定的方法设计PID控制器, 达到抑制负调的作用. 最后, 对飞机的高度俯仰控制进行了仿真验证, 结果表明设计的控制器对飞机高度初始负调具有明显的抑制作用, 并且缩短了回复上升所需的时间. |
| 英文摘要 |
| Vertical or short takeoff and landing(V/STOL) aircraft is a typical non-minimum phase system. The undershoot of the system slows down the height response of the aircraft, and the negative initial stage of the response may also result in undesired fall-out. To solve these problems, a new minimum phase output estimation controller is designed in this paper to improve the dynamic response by adjusting the approximate output zeros, and a PID controller using the two-step parameter tuning method is designed to suppressing the negative regulation. The results of altitude pitch control simulation show that the controller designed here has a significant inhibitory effect on the initial negative adjustment of the aircraft altitude, and the rise time of the height recovery is shorter. |
