stateflow one time step ahead sometimes
显示 更早的评论
Hi,
I built a simple system: ramp - display & stateflow with one input. If I run it, the stateflow is one timestep ahead. If I add another output (still an empty stateflow!) the "discrepancy" is gone. (This is probably just an issue how the display is updated.)
But in my actual model the stateflow sees limits exceeded before the controller (mpc) written in matlab embedded reacts. If I put a unit delay to the statespace input it works fine.
But I have the feeling that this is not a good solution.

It's a little difficult to understand the issue without a model snapshot (if you'd like to upload one, see http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers), but the behavior may be due to the block execution order. See Controlling and Displaying the Sorted Order.
