Simulink is the primary environment in Matlab, which enables us to design, simulate and test various systems. However, in almost every physical system there will be an Algebraic loop. With the complexity of the system the problem with the algebraic loop varies and the techniques reducing these loops are not effective for some systems. Various problems and the techniques which could reduce these problems without affecting the system dynamics are discussed in this book. This book is the enhancement to the FLAVIIR project. An algebraic loop in the model is reduced using various standard techniques and their effectiveness is discussed. It highlights on the combination of discretization and the techniques for algebraic loops can achieve the reduction of an algebraic loop without affecting the system's output.
