Debugging

1. Understand the Problem

  • Start by clearly defining what "debugging" means in the context of the Simulink block
  • Reproduce the issue you're trying to debug
  • Use scopes and displays within Simulink to visualize signals

2. Use Debugging Tools

  • Add breakpoints to your Simulink model
  • Step through the simulation using the Step-by-Step solver
  • Examine workspace variables at different time steps
  • Use the Display block to output signal values

3. Log and Monitor Signals

  • Create subsystems to isolate different parts of your control architecture
  • Add To Workspace blocks to capture signals for post-simulation analysis
  • Plot signals using scopes or MATLAB figures

4. Check Model Configuration

  • Verify solver settings (absolute/relative tolerance, step size)
  • Ensure proper data types and sample times are set
  • Check for algebraic loops and potential zero-crossing issues

5. When Stuck

  • Clear the workspace and start fresh
  • Run a smaller, simplified version of your model
  • Seek help from colleagues or online forums

By following these steps, you can systematically identify and resolve issues within your Simulink control architecture blocks.
