The main goal of this project is study the existence and stability of limit cycles in discontinuous piecewise linear systems obtained by the aggregation of two linear systems of focus type with just one real focus. For this case, we consider an adequate canonical form with five parameters and different bifurcations which are responsible for the appearance of crossing limit cycles. These bifurcation will be studied and in the parameters space will be analyzed some regions with none, one, two or three crossing limit cycles. An bifurcation that appear is the critical crossing cycle and it will be characterized.
