Discover... I am trying to solve it but nothing until now :( –minidiable Aug 27 '15 at 17:22 @minidiable can you clarify please - you have the same loop problem where u1 is a pulse signal or a constant (u1 = 2.5e-6) and u6 = 353 have you any idea about how can i play on this equation ? Any chance you want to share you controller layout or the references you used to build it?

Does the reciprocal of a probability represent anything? In addition to the previous pieces of advice, note that the solver can bealso an issue. Try setting the absolute tolerance to > something else other than auto, e.g. 1e-4. Please help/guide ..
