How for a given signal bound can I plot both my upper and lower limits in the same plot for a given parameter?

I want to use the response optimzer to tune my PID for a given input and I am able to create for the given signal bound. However, my upper bound and lower bound for the respective signal are not in one plot. How can I fix this?

Hi Mohammed Faraan,

When you add a Signal Bound constraint in the Response Optimizer, you can specify both an upper and a lower bound for the same signal.

To plot both upper and lower bounds on the same plot for a given signal, you can try the below steps:

• In the Add Bound dialog, enter the signal name.
• Set the upper bound and lower bound arrays (as vectors or time series matching your simulation time).
• Both bounds are associated with the same signal constraint.

After you add the bound, in the Plots area of the Response Optimizer:

• Right-click the plot.
• Make sure both Upper Bound and Lower Bound are checked to be displayed.
• If only one bound is showing, click the Configure Plots button and ensure both bounds are selected for display.

If you added upper and lower bounds as separate constraints, they may appear in separate plots. In that case, delete the separate constraints and add a new signal bound constraint where you specify both upper and lower bounds at once for the same signal.

This ensures both upper and lower bounds appear together.
