Drones enable us to perform unprecedented feats: see the world from a bird’s perspective, reach remote places thought to be inaccessible, deliver packages or race at incredible speeds. No doubt, drones are awesome pieces of flying hardware, but as all human-made systems, they are prone to failures. At Fusion Engineering, we believe that unprecedented feats require unprecedented levels of safety. Therefore, we put great effort into creating a bulletproof flight control system by employing, among other things, redundant subsystems and Active Fault Tolerant Control (AFTC) methodologies.
This post aims to give a sneak peek to the cutting edge AFTC technologies we leverage in the Fusion Reflex. The emphasis will be on handling faults occurring in the actuators – motor + propeller – of the drone. Let’s start with a comparable example to show what AFTC means in real life.
I hope I could shed some light on how AFTC systems works. It is a close collaboration between an FDD unit and a control system that performs the computation of the required control actions and allocates it to the actuators. We are working hard to integrate the described AFTC system into the Fusion Reﬂex ﬂight controller and our prototype test results allow for healthy optimism for creating the most reliable ﬂight controller on the drone market.
