Hi,
I have the following problem with code on the sliding mode control, solving a non linear problem:
running the code, I do not have errors or warning, the integration starts, but does not end, looks like enter in a sort of infinite loop.
Showing some result in the function and running I realized that:
-- with a tollerance about 1e-13 (I always use this), the results are always equal, so the integration carries on always the same result and it will not go on,
-- reducing thetollerance at 1e-5 , I change see results that change, but integration never end, maybe go to converge, but soon starting to converge.
these happen even if I use a small intervall time.
many many thanks for your time and help
best regards
