Mathematical Model of Pitch Channel of Multi-rotor Aircraft

The multi-rotor aircraft is more and more widely used. In this paper, the mathematical model of Transfer Function is established for the pitching channel model of multi-rotor aircraft. The Transfer Function of the system is an unstable function. Then PID controller is applied to the system to establish the Closed Loop Transfer Function of the system. The stability control of the system is realized by using Routh-Hurwitz criterion and selecting proper PID parameters. Finally, MATLAB is used for simulation.
