Simulink algebraic loop matlab function error
显示 更早的评论
Hi,
I am trying to get around an algebraic loop error (see attached picture). I have an embedded Matlab function that computes the variable dirc, but it requires it's own output as an input (making a loop). I have tried putting in an IC block to give it an initial guess, and I have tried an algebraic constant block, but both have failed. Any suggestions?
Thanks

Dylan,
Algebraic loops happen in these situations where the output of your block directly depends on the input.
If you're running this algorithm at a particular time-step, and can get away with delaying the input dir by one step (i.e., you use the previously calculated value to compute a new output), you should insert a Unit Delay block in the feedback loop from dirc to dir.
