主题

Simulink Control Design

  • Compute Steady-State Operating Points (Simulink Control Design)
    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.
  • Linearize Nonlinear Models (Simulink Control Design)
    Obtain a linear approximation of a nonlinear system that is valid in a small region around an operating point.
  • Choose Linearization Tools (Simulink Control Design)
    Simulink Control Design software lets you perform linear analysis of nonlinear models using a user interface, functions, or blocks.
  • Linearize Simulink Model at Model Operating Point (Simulink Control Design)
    Linearize a model at its operating point consisting of initial state values and input signals.
  • Linearize at Trimmed Operating Point (Simulink Control Design)
    You can linearize a Simulink model at an operating point that meets specified input, output, or state constraints.
