- © 2017 IEEE.This paper addresses practical guidelines for propulsion system design and implementation in a quadrotor micro air vehicle. Due to tiny scale of the motor and propellers required by MAVs, information about features of these devices is frequently unavailable. Therefore, the proposal includes selection of devices, parameter identification and electronic power interface in order to control a motor propeller system. From characterization of the system, thrust and torque coefficients as well as the inertia moment of the motor propeller are obtained, allowing to choose a proper propulsion set according to lift requirements. Furthermore, some aspects for implementing a low level control are presented, including a power interface circuit design based on high efficient consumption of energy criteria, where pulse width modulation is used for implementing some control strategy. The proposed practical guidelines are supported by means of the theoretical and experimental test benches.
