How to simulate a variable DC load using a variable from workspace?

Hi

I want to model a variable DC load (kW) using the values from a variable stored in my workspace. Could anyone help me on how to start with this?

Thanks

Hello,

From my understanding, you want to use the data defined in the MATLAB's workspace while running the simulation.

You can use the 'From Workspace' block to load data from the workspace.

Here are some documentation links which can help you get started:

Thank you for your answer.

I have used the "From Workspace Block" and am able to plot the values using a scope sucessfully. The problem I am facing is how to use this values for the parameters of a simscape block like resistor values.

A Simulink block can have its block parameter value mentioned using a variable.
