The invention provides a dual-redundancy front wheel turning servo system of an unmanned aerial vehicle. The dual-redundancy front wheel turning servo system comprises a servo controller and a turning servo mechanism, the servo controller and the turning servo mechanism are both provided with a main channel and a standby channel, in a normal state, the main channel works, the standby channel follows up, and through a fault monitoring module of the servo controller, when the main channel is monitored to break down, the working channel is switched into the standby channel, and the main channel follows up. When the standby channel is also monitored to break down, the main channel and the standby channel are all cut off and reported to a flight control computer, the reliability of the servo system is effectively improved through the mode, and the all-electric dual-redundancy front wheel turning servo system for the unmanned aerial vehicle has the advantages of being high in reliability, high in motion precision and convenient to maintain by combining mechanical structure research and development; and the requirements of reliability, maintainability, safety and full electrification of the unmanned aerial vehicle are met.

    本发明提供了一种无人机双余度前轮转弯伺服系统,该双余度前轮转弯伺服系统包括伺服控制器和转弯伺服机构,伺服控制器和转弯伺服机构中均有主、备两个通道,正常状态下,主通道工作,备份通道随动,通过伺服控制器的故障监测模块,当监测到主通道发生故障时,将工作通道切换为备份通道,主通道随动。当监测到备份通道也发生故障时,则将主、备份通道全部切除,并上报给飞控计算机,该模式有效提高了伺服系统的可靠性,结合机械结构研发,使无人机用全电式双余度前轮转弯伺服系统具有可靠性高、运动精度高、维护方便的特点,满足了无人机可靠性、维修性、安全性及全电化的需求。
