Abstract
A multicopter rotor fault diagnosis system includes a multicopter, a plurality of local sensors, and a controller. The multicopter includes a body, a plurality of booms secured to the body, and a plurality of rotors. Each boom has a proximal end secured to the body and extends radially outward to a distal end. Each rotor is secured to the distal end of a respective boom. Each sensor is secured to a respective boom and is positioned a distance from the body. The local sensors are configured to measure out-of-plane strain of the booms and to continuously generate boom strain signals. The controller is in communication with the body and the local sensors. The controller is configured to receive the continuously generated boom strain signals and to perform a pattern recognition algorithm to simultaneously detect and identify faults associated with the rotors.
