线性化基础知识

定义要线性化的系统,绘制线性响应,验证线性化结果

您可以在模型中定义的默认工作点处线性化 Simulink® 模型。有关详细信息,请参阅在模型工作点处线性化 Simulink 模型。您也可以指定使用基于优化的搜索找到的工作点或在仿真时找到的工作点。

要提取部分模型的线性化响应,您可以定义特定线性化输入和输出点。有关详细信息,请参阅指定要线性化的模型部分。在线性化后,您可以同时在时域和频域中分析和验证您的结果。

主题

快速入门

  • 线性化非线性模型
    获取非线性系统的线性逼近,该逼近在工作点周围的小区域内有效。
  • 选择线性化工具
    借助 Simulink Control Design™ 软件,您可以使用用户界面、函数或模块对非线性模型执行线性分析。
  • Exact Linearization Algorithm
    Simulink Control Design software linearizes models using a block-by-block approach. The software individually linearizes each block in a Simulink model and produces the linearization of the overall system by combining the individual block linearizations.
  • 在模型工作点处线性化 Simulink 模型
    在由初始状态值和输入信号组成的工作点处线性化模型。
  • Linearize Plant
    You can linearize a block or subsystem in your Simulink model without defining separate analysis points for the block inputs and outputs. The specified block or subsystem is isolated from the rest of the model before linearization.
  • Compute Open-Loop Response
    You can analyze and compute the combined response of the plant and controller, excluding the effects of the feedback loop.
  • Order States in Linearized Model
    You can control the order of the states in a linearized model. This state order appears in linearization results.
