In the paper, solution of the problem of vibrations which appears during the maneuvers of quadrocopters is presented. Those special kinds of vibration aren’t related to mounting or manufacturing faults. In this kinds of flying machines the main sources of vibration comes from motors and/or propellers unbalance. The paper shows analytical description of the source of this problem. Mathematical description of rotor which was subjected of additional rotation had been modeled in MATLAB/Simulink environment. It was shown, that correct set of parameters lead to total elimination of this kind of vibration.

The correct set of parameters in MATLAB/Simulink can eliminate vibrations in quadrocopters caused by motors and/or propellers unbalance.

Analysis of Vibration of Rotors in Unmanned Aircraft

Key Takeaway: The correct set of parameters in MATLAB/Simulink can eliminate vibrations in quadrocopters caused by motors and/or propellers unbalance.
