"Nettet18. jul. 2015 · To break the algebraic loop, you need to insert in the loop a nondirect feedthrough block. The first thing most users think about is a Unit Delay or Memory block. If the blocks in the algebraic loop have a discrete sample time, inserting a Unit Delay is usually the best solution. Of course this will change the dynamic of the system, this is ...
