Unable to supply a 1D array of current to the input of the controlled current source block

Hello,

This is regarding the Simulink Simscape controlled current source block and I face an issue with the current input parmater

I have a 1D array of current supply/demand per second for 608400 timesteps (1x608400 dimension array) in my matlab workspace.

I have a generator and a battery that supplies the demand made by the load. Since I plan to use a 240V system voltage, I am dealing with only current flows to and fro the system.

I am unable to use my current array as an input for the controlled current source block as shows me a dimension error.

I request a solution to this problem or another way of solving it.

I use Matlab version R2020b. I am not sure if this question is asked somewhere, but I hope I get answers for the above problem.

Thanks

Hi Raiyan

I believe that you should use From Workspace blocks. But these need the following format: [time_trace data_trace] so that the temporal aspect is brought to the simulation in addition to the data itself.

Good luck / Juan

Hello Juan,

Thanks for the suggestion

I indeed added another time column to my data array, so now I have a (604800 x 2) matrix where my 1st column is the time in seconds while the second column is the respective data for that timestep and the simulation proceeded smoothly.

But is there a way for having only one dimension array (604800 x1) of data with a timestamp embedded in it? This may ease the process of calculation or data processing in the future.

Thanks and regards,

Raiyan

Hi Raiyan,

Maybe the link: Create timeseries object - MATLAB (mathworks.com) is what you are looking for.

Then, you can use timeseries as data type in the From Workspace block

Thank you so much Juan

This works a lot better now
