Preserving vehicle control and safe landing capability following the sudden loss of an electric motor.
Direct inverter telemetry and Hall effect current sensors detect motor open-circuit or phase-short events in microseconds, immediately preventing back-EMF drag from inducing violent yaw moments on the airframe.
An onboard quadratic programming solver re-calculates the optimal RPM distribution for the surviving motors, compensating for lost lift while maintaining roll and pitch control within 2 degrees of nominal attitude.
