1  Using Arduino / Project Guidance / HELP IN PROJECT USING MATLAB AND SIMULINKā€ on: May 12, 2011, 07:21:16 am
Hello,

I am doing a college project title 'Control of a roll angle of a wing'.  Basically its a model with a pair of wings with a shaft in the middle.  The aim of the project is to stabilize the wings back to their horizontal position if a kick is given on them.

I have a servo motor on the model itself which is connected to the flaps on either side of the wings in order to move them up and down.  I have also a potentiometer attached to the shaft in order to be able to take the reading of the voltage when the wings move up and down.

I am using the MATLAB program for the simulation and I will be also using the arduino as a microcontroller.

My current problem is in the simulink section of this same program.  I am using the arduino target and when I connect the analog input to the scope on the simulink it always reads 0 on it.  What I do is I set the analog input block on the simulink to pin 0 for example and then connect the potentiometer to pin 0.  

The following link is what I am doing in Simulink:

Another problem is that the simulation time goes by too fast (indicated by a circle on the picture).  The sampling time is of 0.001

Can someone please help me with this problem?

Thanks

I am in need of advice regarding my project which is Control of a roll angle of a wing.

I already built the structure consisting of a form of a wing mounted on two poles similar to this:



This is what my structure looks like which I designed using AutoCad:

Can someone please send me some links regarding this project as I have been searching for quite a long time but with no success

Thanks.
