Quadrotor control is often implemented using nested control loops. The inner most loop controls the angular velocities of each axis of the quadrotor. This loop needs to run at a high frequency due to the fast dynamics of the quadrotor. The next highest loop controls the attitude and altitude of the quadrotor.

Förra månaden lanserade DJI sin nya quadrotor-drönare Phantom 3. Den påminner utseendemässigt mycket om storsäljaren Phantom 2 men har fått en rad förbättringar. Nu har Tested provflugit drönaren för att se vad den går för. DJI Phantom 3 finns i två varianter – Professional och Advanced.

Quadrotor Model. The quadrotor has four rotors which are directed upwards. From the center of mass of the quadrotor, rotors are placed in a square formation with equal distance. The mathematical model for the quadrotor dynamics are derived from Euler-Lagrange equations [1]. The twelve states for the quadrotor are:
