| 摘 要： | 无人直升机自动起降是飞行控制过程中的重难点，针对某型无人直升机自动起降阶段出现的特殊问题，考虑质量不确定性以及地效因素的基础上，设计出基于高度的高度控制和基于升降速率的高度控制两种控制方案，通过Matlab仿真和综合仿真对比，说明基于升降速率的高度控制方案能够较好地解决不确定性问题，满足了不同环境下飞行控制性能要求，并提高了控制精度，更适合样例无人直升机起降段的高度控制。

Research of Automatic Takeoff/Landing Height Control Technology for Unmanned Helicopter |

| Abstract: | The automatic takeoff/landing of unmanned helicopter is the key and difficult point in the entire process of flight control,this paper focused on special problems of a certain type of unmanned helicopter automatic takeoff and landing phase.Considering the quality uncertainty and the ground effect factors,two kinds of control laws designing the height control and the lifting speed control were presented.Finally, through the Matlab and integration simulation,the research indicates that the project of lifting speed control is effective and feasible in solving the uncertain problems because it meets the requirement of flight control under different environment and improving the control precision and is more suitable for the sample of un-manned helicopter landing height control. |
