Description

Add-On Required: This feature requires the Simscape Acoustics add-on.

The Controlled Pressure Source block represents an ideal pressure source that is powerful enough to maintain the specified pressure across its terminals regardless of the volume velocity flowing through the source.

The output pressure is p=pT, where pT is the numerical value presented at the physical signal port.
