工作点

从设定(配平)或仿真时间中找到模型工作点,在工作点处初始化模型

动态系统的工作点指定模型在特定时间的初始状态和根级输入信号。您可以使用命令行工具、稳态管理器或在使用模型线性化器线性化模型时查找工作点。有关工作点的详细信息,请参阅About Operating PointsCompute Steady-State Operating Points

稳态工作点

  • About Operating Points
    An operating point of a dynamic system defines the states and root-level input signals of the model at a specific time.
  • Compute Steady-State Operating Points
    To obtain a steady-state operating point, you can trim your model using numerical optimization techniques or simulate your model until it reaches a steady-state condition.
  • Handle Blocks with Internal State Representation
    The operating point object used for linearization and control design does not include Simulink® blocks with internal state representation, such as Memory and Transport Delay blocks.
  • View and Modify Operating Points
    You can view and modify operating point values programmatically at the command line or interactively using the Steady State Manager or Model Linearizer.
