Problem by importing data into simulink as "Array From Workspace"
显示 更早的评论
invalid workspace variable specified as workspace input in 'power_controlcurr/Array From Workspace'. Time values must be non-decreasing.

The error says that the time array t must be consist values in a non-decreasing fashion, Check your time array and see if that fixes the issue.

Hi Anna,
it is difficult to tell why Simulink would error because of a variable having to be non-decreasing when you say it is.
If possible, please upload the model and the required data. Both can be trimmed down to what is needed to reproduce the problem.
Best wishes,
Harald

Hi Anna,
For this Block the "time values must increase monotonically" as stated here in the doc: Load Data Using the From Workspace Block - MATLAB & Simulink (mathworks.com)
In such cases I would reccomend to use the following functions to find out where in a (potentially large) time vector a decrease occurs.
- issorted() to find out if there are non-increasing elements in the vector
- find() e.g.: find(diff(t)<0) to find the effected indecies/lines
Hope that helps,
Nils
