    無人直升機(jī)是一種可在空中自由飛行和懸停的空中機(jī)器人，但無人直升機(jī)的遙控操作卻存在著一定難度。為了簡(jiǎn)化操作步驟，從直升機(jī)操作中最重要的因素“飛行姿態(tài)”入手，設(shè)計(jì)了一套自動(dòng)跟蹤飛行姿態(tài)穩(wěn)定飛行器的控制裝置。為保障系統(tǒng)的穩(wěn)定性，根據(jù)系統(tǒng)可能產(chǎn)生的誤動(dòng)作設(shè)計(jì)了兩種可遙控切換的操作模式。由于各種飛行器的姿態(tài)控制系統(tǒng)相似，因此本裝置具有很強(qiáng)的通用性，可用于其他種類的飛行器進(jìn)行姿態(tài)控制。

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.
