for DRM-SRM; (b) time history diagram for DRM-SRM; (c) phase portrait
for EMRMCS; (d) time history diagram for EMR-MCS.
Figure 6(a) is the phase portrait
in (x, y, z) space and u = 0.
To specify the differences in dynamics of dsk [M.sub.n] parameter a phase portrait
for each sportsman was drawn.
The bifurcation diagram, phase portrait
, and power spectrum are conducted to demonstrate that periodic motions and chaotic motions occur in nonlinear vibrations of the rotating blade under certain conditions.
The phase portrait
of system (39) is shown in Figure 1.

of system (1a), (1b), and (1c) for a = 3.3 and b = 3.
Figure 7 shows the phase portrait
of susceptible hosts S(f) and infectious hosts 7(f) of system (2) when [tau] = 30 < [[tau].sub.0].
In this region, each response was characterized using a phase portrait
, a Poincare map (velocity versus phase angle), and a frequency spectrum.
If c [less than or equal to] -2,0 is an unstable node, and the global phase portrait
is shown in Figure 1(a); if -2 < c < 0, O is an unstable focus, and the global phase portrait
is shown in Figure 1(b).
Taken g = 0.5, the phase portrait
, time course diagram and the Poincare map of the controlled system are shown in Fig.
It can be seen from the analysis and simulations above that the improved Lorenz-like chaotic circuit can only output three chaotic waveforms and three chaotic phase portraits
. What is more, it can only output inverted phase portrait
shape like butterfly wings.
