s型速度曲线的MATALB代码

Sure! Here's an example of MATLAB code to plot an S-shaped velocity curve:

% Input parameters
Vmax = 10;   % Maximum velocity
t_acc = 2;   % Time taken to reach maximum velocity
t_dec = 2;   % Time taken to come to rest
dt = 0.01;   % Time step

% Calculate time intervals
t_total = t_acc + t_dec;                   % Total time
t1 = linspace(0, t_acc, t_acc/dt);         % Time interval for acceleration phase
t2 = linspace(t_acc, t_total, t_dec/dt);   % Time interval for deceleration phase

% Calculate velocity for acceleration phase
V1 = (Vmax/t_acc) * t1;

% Calculate velocity for deceleration phase
V2 = Vmax - (Vmax/t_dec) * (t2 - t_acc);

% Concatenate time and velocity arrays
t = [t1 t2];
V = [V1 V2];

% Plotting the velocity curve
plot(t, V);
xlabel('Time');
ylabel('Velocity');
title('S-shaped Velocity Curve');

This code will generate a plot showing the S-shaped velocity curve. You can adjust the input parameters `Vmax`, `t_acc`, `t_dec`, and `dt` to customize the curve according to your requirements.
