PS Constant Offset Estimator

R2026b

Measure constant offset value of periodic signal

  • PS Constant Offset Estimator block

Libraries:
Simscape / Foundation Library / Physical Signals / Periodic Operators

Description

The PS Constant Offset Estimator block measures the constant offset value of a periodic signal.

A signal is periodic if it completes a pattern within a measurable time frame, called a period, and repeats that pattern over identical subsequent periods. The signal base frequency is the number of periods per second.

The constant offset is the amount by which the average value of the periodic signal is not centered around the t-axis.

Both the input and the output are physical signals. Untyped physical ports facilitate unit propagation. The output signal has the same physical unit as the input signal.

To obtain meaningful results, run the simulation for at least one full time period of the signal.

Ports

Input

Input physical signal. The signal must be periodic.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Programmatic Use

Port: I

Output

Output physical signal.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Programmatic Use

Port: O

Parameters

Base frequency of the periodic signal.

Programmatic Use

Parameter: f0

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/Physical Signals/Periodic Operators/PS Constant Offset Estimator"

Example: add_block("fl_lib/Physical Signals/Periodic Operators/PS Constant Offset Estimator","myModel/myBlock",MakeNameUnique="on")

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