Multi-rotor unmanned aerial vehicle control system

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle control system, which comprises a main control module, a sensing module, an execution unit and a power supply module, wherein the sensingmodule comprises an inertial measurement unit, an air pressure height measurement unit and a GPS unit; the execution unit comprises a motor and a plurality of pitch control units; the motor is used for simultaneously driving a plurality of rotors to rotate; the pitch control units are used for the pitches of the rotors, the pitch control units change the angle of the rotors through a steering engine, the sensing module and the execution unit are respectively connected with the main control module; the power supply module comprises a solar panel, a storage battery, a charging management unit and a voltage detection unit. The system adopts one motor to control the plurality of rotors, and only the pitches of part of the rotors need to be controlled and changed when the attitude of the unmanned aerial vehicle needs to be adjusted, so that the flight control of the unmanned aerial vehicle can be achieved, the energy consumption of the unmanned aerial vehicle is reduced, and the endurance capability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle control system. Background technique [0002] With the advancement of science and technology and the opening of the low-altitude field, multi-rotor UAVs are more and more widely used in military and civilian fields. Various research institutions at home and abroad have launched corresponding research and development work on UAVs. The existing multi-rotor UAV is an electric control and can take off and land vertically. For example, the common four-rotor UAV has a compact structure and can generate a large lift. The four rotors can offset each other's reverse torque. torque without the need for a dedicated anti-torque propeller. Traditional quadrotor UAVs usually control the attitude and movement by changing the speed of the propellers, so four motors are required to work at the same time. This control method often increases p...
