CL Discrete Second Order Low Pass Filter

CL Discrete Second Order Low Pass Filter

Owning Palette:Discrete

Requirements:Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer, Control Design and Simulation Module


Description

Models, in the discrete-time domain, a second-order low-pass filter characterized by a cut-off frequency and a damping ratio.


Outputs

y

y is the (filtered) output signal from the second-order low-pass filter.

yd

yd is the time-derivative of the output signal from the second-order low-pass filter.


Details

The CL Discrete Second Order Low Pass Filter VI models, in the discrete-time domain, a second-order low-pass filter characterized by a cut-off frequency and a damping ratio. The filtered output is always continuous even after any parameter change (e.g., cut-off frequency and/or damping ratio).

The block diagram for this VI is shown below:

where ωn is the cut-off frequency and ζ is the damping ratio.


Feedthrough Behaviour

All input/output pairs of this function have direct feedthrough behaviour.
