Operating Points

Find model operating point from specification (trimming) or simulation time, initialize model at operating point

An operating point of a dynamic system specifies the initial states and root-level input signals of the model at a particular time. You can find operating points using command-line tools, the Steady State Manager, or when linearizing a model using the Model Linearizer. For more information about operating points, see About Operating Points and Compute Steady-State Operating Points.

Steady-State Operating Points

  • 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.
