Description

The External Translational Velocity Source (PB) block represents an ideal external velocity source that generates a specified velocity regardless of the load at the connected port.

Port R is a position-based translational conserving port. Specify the velocity at physical signal port S. A positive signal at port S applies a positive velocity to the network at port R.

The block logs the variable f, which represents the force applied at port R to generate the specified velocity. A positive force corresponds to acceleration in the positive direction. For more information, see Data Logging.

Ports

Input

S — Control signal, m/s

physical signal

Physical signal input port for the control signal that drives the source. A positive signal at this port applies a positive velocity to the network at port R.

Programmatic Use

Port: S

Conserving

R — Port that applies external velocity to the network

position-based translational

Position-based translational conserving port that connects the block to the circuit and applies the external velocity to the physical network.

Programmatic Use

Port: R

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"fl_lib/Translational/Sources/External Translational Velocity Source (PB)"

Example: add_block("fl_lib/Translational/Sources/External Translational Velocity Source (PB)","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
