simulink control re entry atmosphere code

Hi, I am trying to do this simulation, is a control of a re-entry vehicle. I have a nominal trajectory that comes from an optimization. and know I am trying to implement a control that follows this tracjectorie. but I have this error, I am sure that is very simple but I do not find the solution in the documentation, and so I can,t go on.

"Invalid structure-format variable specified as workspace input in 'entry/From Workspace'. If the input signal is a bus signal, the variable must be a structure of MATLAB time series objects. Otherwise, the variable must include 'time' and 'signals' fields, and the 'signals' field must be a structure with a 'values' field."

many thanks for your time and consideration.

kinds regards

When I loaded the given *.mat files the variables phin, rn, vn are actually stored as 1x1 struct, which is why errors are coming up.

So, after you load the *.mat files, run the following command:

phin = phin.mat;

rn = rn.mat;

vn = vn.mat;

Now, run your entry.slx model and also please change the phin’ to phin in your Simulink model.

Hope this helps!
