I tried to plot it in Xppaut but it didn't work. So now I am trying to do in Matlab. Because of my system, I can't draw bifurcation diagram directly and I searched online and I found a code (that was shared by Suneel Madhekar) for the (approximate) bifurcation diagram based on Poincare sections obtained on the Y=0 plane.
Jun 04, 2018 · Sketching some of these in will give the following phase portrait. Here is a sketch of this with the trajectories corresponding to the eigenvectors marked in blue. In this case the equilibrium solution $$\left( {0,0} \right)$$ is called a saddle point and is unstable.
If $$\dot{q}=u(q,p,t)$$ were identically satisfied, even on arbitrarily varied phase-space paths, then $$L_{ph}$$ would simply be $$L$$ expressed in phase-space coordinates. However, one can easily construct a counter example to show that this is not the case: consider a variation of the path in which we can vary the direction of its tangent ...
Plot of the disturbance model, called noise spectrum. This plot is the same as a Bode plot of the model response, but it shows the output power spectrum of the noise model instead. For more information, see Noise Spectrum Plots. (Only in the MATLAB ® Command Window) Nyquist plot. Plots the imaginary versus the real part of the transfer function.

Sep 10, 2004 · In two dimensions, the phase space plot corresponding to the normalized matrix spans from -1 to +1 on either axis. The phase space area is now divided into small square areas of size { R × R | R ∈ Real, 2/R ∈ Integer }. Then the number of grids in the normalized phase space is n = 2/ R.

Phase plane! In the study of dynamic systems (such as the Lotka-Volterra competition model) it can be very useful to visualize the system on the phase plane.. To do this, we envision the abundance of each interacting species as a coordinate in a cartesian plane, with one species as the y axis and the other species as the x axis.
ODE solvers for nonlinear differential equations. Phase portrait. This section, we will show built-in commands in MATLAB used for solving differential equations. Finding a numerical solution of a PDE is an advanced topic. In this document, we will cover how to solve ODE only.
Although Poincaré plots are among the simplest representation of a system’s phase space , they may provide important information about the dynamics. For illustration purposes here we use heartbeat time series, i.e., a sequence of consecutive ventricular interbeat (QRS) intervals (termed RR) intervals obtained from an electrocardiographic ...

Here is the code I used: b = [2 0 3.125]; % numerator coefficients a = [1 -0.9 0.81]; % Denominator coefficients freqz (b, a); I strongly suggest you to read the freqz documentation to see why we put the parameters in such a way and to find other options.
