This simulink model simulates the damped driven pendulum, showing it s chaotic motion. theta = angle of pendulum omega = (d/dt)theta = angular velocity Gamma(t) = gcos(phi) = Force omega_d = (d/dt) phi Gamma(t) = (d/dt)omega + omega/Q + sin(theta) Play with the initial conditions (omega_0, theta_0, phi_0 = omega(t=0), theta(t=0), phi(t=0)) and the system parameters (g, Q, omega_d) and the solver parameters/method. Chaos can be seen for Q=2, omega_d=w/3. The program outputs to Matlab time, theta(time) & omega(time). Plot the phase space via: plot(mod(theta+pi, 2*pi)-pi, omega, . ) Plot the Poincare sections using: t_P = (0:2*pi/omega_d:max(time)) plot(mod(spline(time, theta+pi, t_P), 2*pi)-pi, spline(time, omega, t_P), . ) System is described in: "Fractal basin boundaries and intermittency in the driven damped pendulum" E.

频谱分析实践，将信号源发出的信号强度按频率顺序展开，使其成为频率的函数，并考察变化规律，称为频谱分析。研究噪声的频谱是为了深入了解噪声源的特性帮助寻找主要的噪声污染源，为噪声控制提供依据，为噪声控制提供依据。(Spectrum analysis practice, the signal strength of the signal source frequency in order to start by making it a function of frequency, and variation study, known as spectrum analysis. Of the noise spectrum is to understand the characteristics of noise sources to help find the major noise sources, provide the basis for the noise control, provide the basis for the noise control.)
