Modeling Sigma-Delta Modulator Non-Idealities in SIMULINK

通过matlab模拟半导体激光器的动力学特性，通过调节反馈强度可以得到从弛豫震荡到混沌态的输出信号。(Matlab simulation by the dynamics of semiconductor lasers, can be obtained by adjusting the intensity of the feedback from the chaotic state of relaxation shocks to the output signal.)

2FSK调制matlab仿真程序，不同调制指数下幅频特性(2FSK modulation matlab simulation program, amplitude modulation characteristics under different modulation index)

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.
