i want to try to convert the duty cycle data into derive cycle. For that i'm creating a variable in workspace time_power. i'm getting this error.

Error:Invalid workspace variable 'time_power' specified as workspace input in 'drive_cycle_current/From Workspace'. Time values must be a real vector.

Hi Garvit,

Though you have mentioned the error message that you are encountering, it is still not clear of the approach/code that you are using to create a time vector.

Looking at the error mesage, it seems that the format of the data you are trying to import doesn't match with what Simulink expects. To create and load data that includes time values using the 'From Workspace' block, the data type for the time values must be double and the time values should be non-decreasing.

To further understand how to create and load time values using the 'From Workspace' block, you can refer to the following documentation:

Here are a couple of MATLAB answers with similar error messages:

Hope this helps!
