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?
