Owning Palette: System Identification VIs

Requires: System Identification Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Data Preprocessing VIs to preprocess the raw data that you acquired from an unknown system.

The VIs on this palette can return general LabVIEW error codes or specific System Identification error codes.

Palette ObjectDescription
SI Bandpass FilterApplies a bandpass filter to stimulus and response signals. Wire data to the signal in and stimulus signal in inputs to determine the polymorphic instance to use or manually select the instance.
SI Detect FeedbackDetects if feedback exists in a system using the impulse response of the system. Wire data to the stimulus signal and response signal inputs to determine the polymorphic instance to use or manually select the instance.
SI Down SamplingReduces the sampling rate of stimulus and response signals using decimation. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance.
SI Lowpass FilterApplies a lowpass filter to stimulus and response signals. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance.
SI NormalizeNormalizes the stimulus and response signals so that their mean and standard deviation are 0 and 1 respectively. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance.
SI Rebuild Missing DataRebuilds corrupted or missing parts of stimulus and response signals. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance.
SI Remove TrendRemoves mean and linear steady-state trends from stimulus and response signals. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance.
SI Split SignalSplits stimulus and response signals into two parts. Use one set of signals for model estimation and one for model validation. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance.
