Matlab中Simulink中的信号生成模型 [英] signal generation model in Simulink from matlab

问题描述

如何在simulink中生成以下信号:

How do I generate following signal in simulink:

t=(0:1000)/1000*10*pi; 

我要构建以下matlab代码的模型:

I want to build the model of the following matlab code:

t=(0:1000)/1000*10*pi; 
x = (t).*sin(t);
y = (t).*cos(t);
z = t;

推荐答案

这是相当基本的东西.您是否已阅读过Simulink的任何教程，介绍视频/网络研讨会甚至文档的入门指南?

This is fairly basic stuff. Have you gone through any Simulink tutorial, introduction videos/webinars or even the getting started guide of the documentation?

这里有一些建议可以帮助您回答问题:

Here are a few suggestions to help you answer your question:

1. 将模型的停止时间设置为1000s，并使用步长为1s的固定步长求解器.
2. 使用抽取值为1的时钟块.那就是你的0:1000向量.
3. 将Clock块的输出输入到增益块，增益设置为1/(10000*pi).那就是你的t向量.
4. 将您的t信号输入到两个三角函数块，一组设置为sin，另一组设置为cos.这将生成两个信号sin(t)和cos(t).
5. 现在使用t信号与sin(t)信号相乘. > Product 块，以生成您的x信号(t*sin(t)).
6. 对t和cos(t)执行相同的操作以生成您的y信号. z已经完成，因为它等于t.

1. Set the stop time of your model to 1000s and use a fixed-step solver with a step time of 1s.
2. Use a Clock block with a decimation of 1. That's your 0:1000 vector.
3. Feed the output of your Clock block to a Gain block, with the gain set to 1/(10000*pi). That's your t vector.
4. Feed your t signal to two Trigonometric Function blocks, one set to sin and one set to cos. That will generate two signals, sin(t) and cos(t).
5. Now multiply your t signal with your sin(t) signal using a Product block, to generate your x signal (t*sin(t)).
6. Do the same thing with t and cos(t) to generate your y signal. z is already done since it's equal to t.

编辑以下评论

您的评论的答案实际上是Simulink的基本内容.在尝试在Simulink中进行VR等高级操作之前，您应该学习如何使用Simulink.有点像在跑步之前先跑步.

The answer to your comment is really basic Simulink stuff. You should learn how to use Simulink before trying to do advance stuff like VR in Simulink. It's a bit like trying to run before you can walk.

我对VRML不太了解，但是请注意VRML中的坐标系与MATLAB/Simulink中的坐标系不同(请参见

I don't know much about VRML, but be aware that the coordinate system in VRML is different from that in MATLAB/Simulink (see http://www.mathworks.co.uk/help/sl3d/vrml.html). You should also have a look at Virtual World Connection to a Model in the Simulink 3D Animation documentation.
