    无人直升机是一种可在空中自由飞行和悬停的空中机器人,但无人直升机的遥控操作却存在着一定难度。为了简化操作步骤,从直升机操作中最重要的因素“飞行姿态”入手,设计了一套自动跟踪飞行姿态稳定飞行器的控制装置。为保障系统的稳定性,根据系统可能产生的误动作设计了两种可遥控切换的操作模式。由于各种飞行器的姿态控制系统相似,因此本装置具有很强的通用性,可用于其他种类的飞行器进行姿态控制。

 


 

Study on Stability Device of  Unmanned RC Helicopter in Changing Flight Attitude (pitch and roll)

Unmanned helicopter is a kind of aerial robot in the sky. However, It is difficult to operate the unmanned helicopter remotely. In order to simplify the operation, I inputted Zero-signal into the feed back circulation of original ‘co-pilot CPD4’. And use them as a standalone closed control system. Now, the purpose of this standalone closed control system is to keep the helicopter into horizon. Then, I want it to follow the attitude signal which is send from operator automatically. I design and make a two axes mechanical radio control attitude setting system, this mechanical system can set an angle between the infra-red attitude detect sensor and the main rotor. Two systems worked together (closed control system & attitude signal setting system) in order to form a novel flight attitude control system, this system can control and Stabilize the flight attitude automatically according to the attitude signal that I send to it. So control the attitude of RC helicopter with this system (Device) is just like taking it you’re your hands (with the original control system, operator can just control the attitude movement. But with this device, operator can use transmitter to set an attitude signal, the attitude movement of helicopter will be controlled by this device automatically).


After many practice I realized, the attitude control systems are similar in many aircrafts, so it can be used in Stabilizing pitch and roll for almost any R/C aircraft.
