Simulink Control Design™ - MathWorks

Choose Operating Point Search Tools

Simulink Control Design lets you search for operating points of your Simulink model

programmatically at the command line and interactively in two graphical tools.

Search Tool When to Use

findop • Programmatically compute operating points

• Compute operating points from specifications


• Find operating points at simulation snapshots


• Batch compute operating points for multiple
  specifications


• Batch compute operating points for parameter
  variations
  Steady State Manager • Interactively compute operating points


• Compute operating points from specifications


• Validate operating point search results against
  specifications


• Find operating points at simulation snapshots


• Generate MATLAB® code for computing operating
  points. This code can be reused for batch computation.
  Linear Analysis Tool • Interactively find operating points within a
  linearization context


• Compute operating points from specifications


• Find operating points at simulation snapshots

Trimming Using Simulink Control Design Versus Simulink

Simulink provides the trim command for steady-state operating point searches. However,

findop in Simulink Control Design provides several advantages over using trim when

performing an optimization-based operating point search.
