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.

说明：  matlab实现陷波器，采用的是LMS 算法实现，能将特定的正弦信号滤去(matlab notch filter realization using the LMS algorithm, the sinusoidal signal to a particular least squares)

主成分分析的代码，数据处理的必备，方便实用！！(Principal component analysis of the code, the data processing required, convenient and practical! !)

很不错的目标跟踪轨迹模拟MATLAB仿真程序，可以在MATLAB0.7运行成功(Good target tracking trajectory simulation of MATLAB simulation program, can run in MATLAB0.7 success )

本程序是针对左端铰支，右端固支的连续梁，并且其中的集中荷载是按作用点在单元中点计算。对于初学者可以做为参考。(This program is for the left end of the hinge support right end clamped continuous beam, and the concentrated load action point unit midpoint. Can be used as a reference for beginners.)

模态分析程序，一定要有实验现场的数据，要不运行不了(Modal analysis program, there must be experimental field data, or not running)
