Hi,

I am running a PI control structure in Simulink. I want to create one set of axis with multiple graphs, allowing me to show comparison of the system response with different PI control parameters.

I am unsure on how to do this. I am aware of the Simulink data logging function, which creates a data set of a specific variable that can be found in the workspace of matlab.

I also understand how to obtain a plot of a variable in the worskpace of matlab by simply clicking the plots tab.

However, since I am running my simulink model multiple times and obtaining the same variable data set each time, I find that my data from the past run gets overridden. Is there any way I can permanently store the data from each run, so this doesn't happen?

Alternatively, is there a way to export data from the workspace into excel? This would be simpler.

Thanks
