Figure 8: The chaos control of system A$_{3}$. It is observable in the figure that controlling the chaos of system A$_{3}$ makes the chaos of system A$_{2}$ to be also controlled. Figure 9: The stabilized quasi-periodic solution of system A$_{3}$. Figure 10: The stabilized torus of system A$_{3}$. to system A$_{2}$ makes an unstable quasi-periodic solution of A$_{3}$ to be stabilized. On the other hand, the stabilized torus of system A$_{3}$ is shown in Figure 9. This section considers the phenomenon of chaos extension by utilizing an economical model with time lag (5.15). We are devoting a separate discussion to this model, since the result for this case does not have theoretical support at the moment. The extension of chaos can be only observed numerically in our example, but in the future one could prove the entrainment of the limit cycle by chaos for functional 5 Chaotic Business Cycles in Kaldor-Kalecki Model with Time Delay 16 0 50 100 150 200 250 300 350 400 450 500 0.9 1.1 1.3 t y 2 200 210 220 230 240 250 260 270 280 290 300 1.144 1.145 1.146 1.147 t y 2 0.12 0.124 0.128 0.132 0.0834 0.0836 0.0838 0.084 1.144 1.145 1.146 1.147 1.148 y$_{1}$ k$_{1}$ y 2
