The methodology of the analyses consists in utilization of the following tools\: color maps of distribution of the maximal Lapunov coefficient and bifurcation diagrams. Based upon them, the parameters were determined, for which the Poincare portrait represents a structure of the chaotic attractor. For the identified attractors, the initial attractors were calculated numerically \- which along with the changes of the control parameters are subjected to multiplication, stretching or rotation."]
