According to the reliability requirement of the Flight Control Computer for Unmanned Aerial Vehicle (UAV), a design scheme is proposed to ensure its reliability by using tri-redundancy technology. Further, by selecting appropriate redundant mode and the architecture model of the triple redundant flight control computer is established in this paper....

... the synchronous signal of the other two computers is not collected within 50 micro-seconds, it can be interrupted to judge whether it cannot be synchronized for 10 consecutive times, and if it is, it can be put into single-machine working mode. Figure 5 is a diagram of narrow-amplitude pulse signals sent periodically (10ms period) by three channels of the flight controller. After synchronization, the narrowamplitude pulses can be sent out at the same time the handshake protocol completely solves the problem of synchronization. ...

Tracking position and orientation independently affords more agile maneuver for over-actuated multirotor Unmanned Aerial Vehicles (UAVs) while introducing undesired downwash effects; downwash flows generated by thrust generators may counteract others due to close proximity, which significantly threatens the stability of the platform. The complexity...
