Include timeseries data from workspace in Simulink and activate them by trigger during simulation

7 views (last 30 days)
I want to include some timeseries data (which always starts at t=0) from my workspace into simulink. By a specific trigger, the data shall be evaluated during simulation. The data shall be start at t=0 even when the simulation time is not equal to zero. I tried this with a look-up table, but due to a variable step solver the results are falsified. Are there other solutions for including such data?

In general, timeseries data must go hand-in-hand with the current time of the simulation. So unfortunately, having the data evaluated at t = 0 even when the simulation time is not 0 would not be possible directly.
One workaround would be to change the format of the data. Using multiple vectors/arrays instead of a timeseries would probably better.
For example, you could put the timeseries data into vectors, and then use constant blocks that reference a specific index of the array that changes with respect to time.
