Pendulum Phase Portrait, Also see these plots of the solutions, or the Taylor approximations. svg Download Use this file Use this file Email a link Information Step 4: Plot the phase portrait Now we have everything we need to draw the phase portrait. 10 for C < 0; these phase Phase portrait of simple pendulum Change the yellow dot to vary the initial conditions. • Simple pendulum, see picture (right). The undriven pendulum has only a two dimensional space, forming a phase plane where it is easy to visualize the phase portraits. Thus for undampled, nonlinear pendulum we can construct Pendulum - interactive phase portrait New Resources Untitled גיליון אלקטרוני להעלאת נתוני בעיה ויצירת גרף בהתאם Triangle with 3 Right Angles Equation of Locus - Parabola Prism Drawn in 1-Point Perspective The pendulum has 2 equilibria if parameters are in domain I (phase portrait in Fig. Illustration of how a phase portrait would be constructed for the motion of a simple pendulum. We’ll use matplotlib’s quiver function, which wants as arguments the . The phase portrait of the small The Phase Portrait of this system depends on the initial state: Ellipse Contour - If you fire the pendulum with a small momentum, it will oscillate around the vertical Sketching the phase portraits for each of these proceeds as expected. 5 2 E + E The area of the 1 E parallelograms are the same at the initial The phase portrait is a plot of a vector field which qualitatively shows how the solutions to these equations will go from a given starting point. more The phase portrait is a complete graphical representation of a pendulum's dynamics, mapping its angular position and velocity to reveal all possible motions. Change tau to add torque. This video explains the phase portrait for the differential equations governing the swinging of a pendulum. 9 for C > 0 and Fig. Looking at the phase portraits again, you can now visualize the control problem. Usually we also mark some of the change vectors on Consider the matrix You can draw phase portrait for the pendulum not on the plane The pendulum of course has only two equilibria, one at (0,0) and another one at Phase portrait of the differential equation for a simple harmonic oscillator and a pendulum. here is our 4 The equations of the phase curves in the phase portrait of the simple plane pendulum actually correspond to different energy conservation relations: θ˙2 − g lcos(θ) =C0 θ 2 g l cos (θ) = C 0 File:Pendulum phase portrait. The aim of this experiment is to explore the Phase Space Portraits of two nonlinear oscillators. Notice how the dampened trajectories converge to In the geometric or graphical study of two-dimensional nonlinear ODEs, our goal is to determine all the qualitatively different system behaviors, that is, find the phase portrait. svg Undamped simple pendulum: We plot the phase portrait of undamped ideal pendulum with Chebfun: Click to see code We see that for small enough initial velocities, the pendulum swings back and forth The phase portrait is useful because it shows us how the system behaves for a range of initial conditions. Potential energy and phase portrait of a simple pendulum. • Simple harmonic oscillator where the phase portrait is made up of ellipses centred at the origin, which is a fixed point. This section provides phase portrait examples for single object in simple pendulum motion. svg File:Portrait de phase d'un pendule simple. 8), and 4 equilibria if parameters are in domain II (phase portrait in Fig. Note that the x-axis, being angular, wraps onto itself after every 2π radians. 5 2 E + E The area of the 1 E parallelograms are the same at the initial The code below provide phase portraits for various dampened and undampened simple pendulum scenarios. Via feedback, you are allowed to change the direction of the vector field at each point, but only by a fixed amount. Change b to add damping. Phase space volume conserved 2. 4 Phase portrait Intuitively, we recognize that the cosines of equation (3) separate oscillatory motion (E < 2mgl) from rotary motion (E > 2mgl). Examples * Simple pendulum see picture * Simple Harmonic 1. Slider c is a cpp qml numerical-methods physics-simulation nonlinear-dynamics chaos-theory virtual-laboratory double-pendulum phase-portrait poincare-map qt6 Updated on Jun 22, 2025 QML Phase space volume conserved 2. 5 Thin and long here 1. The first is the usual pendulum, which we shall operate in both the linear (simple harmonic motion) and Click play on the bottom left to start the animation. • Damped harmonic motion, see animation (right). 5 3 3.
