How to connect a dc motor simulink model into a structure of simmechanics?
9 views (last 30 days)
Hello! I have a simulink model of a solar tracker, and the output is the angular position of a dc motor which rotates a solar panel. I have a CAD model of a solar tracker and i want to import it to simechanics. Wha t i have to do is relate the motor angular position to the joint where the motor is? Also, in the transfer function of the motor, i inlcuded the inertia of the motor+tracker's structure, and in the torque term i used motor torque-load torque. Now that i am going to connect it to a simmechanic model, are the torque and inertia automatically computed so do i have to remove them from the simulink equation? Any help would be appreciated.

what you are suggesting goes in the right direction. We do have a multibody example of solar panel tracking if you want some Multibody files to prototype:
Regarding your question:
We released a free blockset addon with example of blocks that connect 1D simulation with 3D simulation in Simscape:
For older release than 20a look at the link in the File Exchange entry:
There is even a DC motor with Multibody ports that you can apply to move a rotational joint:
After you have looked at the example I believe you are going to understand properly the connection of 1D with 3D. You need to create a kinematic relationship between the components, here the screenshot fro mone of the example:
Hope that helps
