一、简介

钟摆是一种经典的物理系统，因其简洁性和对复杂动态行为的展现而备受关注。基于MATLAB GUI和Simulink，我们可以轻松构建钟摆的自由控制仿真模型，并对其行为进行深入研究。

二、源代码

源代码如下所示：

% Define system parameters
L = 1; % Length of the pendulum (m)
m = 1; % Mass of the pendulum (kg)
b = 0.1; % Damping coefficient (Ns/m)
g = 9.81; % Acceleration due to gravity (m/s^2)

% Create Simulink model
pendulumModel = simulink.sldemo.pendulum;

% Set simulation parameters
simTime = 10; % Simulation time (s)
solver = 'ode45'; % Solver to use

% Run simulation
simOut = sim(pendulumModel, 'StopTime', simTime, 'Solver', solver);

% Plot results
figure;
plot(simOut.tout, simOut.yout(:, 1));
title('Pendulum Angle');
xlabel('Time (s)');
ylabel('Angle (rad)');
grid on;

figure;
plot(simOut.tout, simOut.yout(:, 2));
title('Pendulum Angular Velocity');
xlabel('Time (s)');
ylabel('Angular Velocity (rad/s)');
grid on;
