Modelling a Quadrotor with Simmechanics

Guys it's possible to model a plant of a quadrotor using simmechanics? For instance which kind of joint I can use to model the force(F1,F2,F3,F4) of the quadrotors

Or maybe I'm going on the wrong direction and for this the best would be the aerospace blockset?

Thanks

Guys this is the first test with the Assembly (Propeller + Motor) from solidworks to simmechanics with the External Force and Torque

Simulation Video

Just to confirm this is the idea???

Nice!Could you tell me how to model the brushless motor and the propeller? Thanks!

Depending on what you're looking to do, this can be done with either Aero Blks or SimMech. From scratch, aero blks is easier because you can simply create the force and moment on a moment arm assuming the CG is directly centered. However, if you have a CAD model, I would import it into SimMech 2G and generate the forces using simscape blocks.

Hi guys I've added the project here on file exchage .... http://www.mathworks.com/matlabcentral/fileexchange/44902-quadrotor-modelling-and-control-with-simmechanics

Hi Leonardo,

Do you have the XML file of the qudcopter (that can be imported by SimMechanics) that's exported from Solidworks? I would like to use it to design my controller?

Thank you.

Hi Mohamed i've added this project on the filéexchange with the solidworks project included.

Dear Leonardo, i saw your simmechanics blocks. they are amazing, i am also actually working on a quadcopter, i would like to know how did you make the quads roll and pitch at respective time intervals. i actually used yours as my reference and i made one, but my quads respons is very slow can you please help me in that thanks

Hi @Leonardo Araujo, You can do the CAD modelling in Inventor/Solidoworks and import the model into simulink. This way it would be much easier and for Forces, you can use the blocks, External Force/Toruques.

May be you can try using BLDCM.
