CHAPTER 4 (C4 Folder) TRANSFORMERS Project 1: Short-circuit and RL Load Terminations SIMULINK file s1a.mdl (linear transformer) SIMULINK file s1b.mdl (piece-wise linear saturation) SIMULINK file s1c.mdl (lookup table saturation) MATLAB M-file m1.m MATLAB M-file fftplot.m (fftplot.m should be placed in a directory on MATLAB s search path) Project 2: Open-Circuit Termination, In-rush Current, and DC Bias Core Saturation SIMULINK file s1c.mdl (lookup table saturation) MATLAB M-file m1.m Use the given FFTPLOT.m to obtain the discrete Fourier transform

说明：  MATLAB实现遗传算法求函数最大值，可以改变变量数目，函数形式(Seeking maximum MATLAB Genetic algorithms function, you can change the number of variables, functional form)

matlab编程教程，适用于初学者，是很好的国外教材(Essentials of MATLAB Programming)

with this mscripts we are enable to perform accurately pitch detection.first with short term zerocrossing and short term energy estimation analyses we find voiced regions and then with hps algorithm, find pitch values of utterance.

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.
