Stabilization of a Four-Rotor Mini-Rotorcraft

Civil and military applications of autonomous flying vehicles have been steadily increasing over the last few years. Four-rotor mini-rotorcraft is one of them and applied wildly in many scenarios which require high vantage and mobility, for instance, fire rescue and military reconnaissance. The uncertain meteorological factor in the air is a great challenge for the stabilization of the mini-rotorcraft. We use the PID controller to adjust the attitude of mini-rotorcraft at the price of high calculating amount in MCU. The accuracy and sensitivity of the transducer will also cause the delay during the signal transmission and finally result in the body-shaking. In this passage we apply gyroscopic effect of the rotor wing to enhance the stabilization of the fuselage by install an accessory on each rotor wing. Also, change the vertical angle of the rotation shaft can transform sideways force caused by Horizontal wind into lifting power.
