CD Evaluate at Frequency VI

Owning Palette: Frequency Response VIs

Requires: Control Design and Simulation Module

Determines the magnitude and phase of the system at the given frequency. Wire data to the State-Space Model input to determine the polymorphic instance to use or manually select the instance.

Details  

CD Evaluate at Frequency (State-Space)

State-Space Model contains a mathematical representation of and information about the system for which this VI determines frequency response.
Frequency (rad/s) is the frequency at which this VI evaluates the system to obtain the magnitude and phase. The default is 0.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Response returns the complex number that this VI obtains by evaluating the system at Frequency (rad/s).
Magnitude returns the magnitude of Response in decibels.
Phase (deg) returns the phase in degrees of Response.
error out contains error information. This output provides standard error out functionality.

CD Evaluate at Frequency (Transfer Function)

Transfer Function Model contains a mathematical representation of and information about the system for which this VI determines frequency response.
Frequency (rad/s) is the frequency at which this VI evaluates the system to obtain the magnitude and phase. The default is 0.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Response returns the complex number that this VI obtains by evaluating the system at Frequency (rad/s).
Magnitude returns the magnitude of Response in decibels.
Phase (deg) returns the phase in degrees of Response.
error out contains error information. This output provides standard error out functionality.

CD Evaluate at Frequency (Zero-Pole-Gain)

Zero-Pole-Gain Model contains a mathematical representation of and information about the system for which this VI determines frequency response.
Frequency (rad/s) is the frequency at which this VI evaluates the system to obtain the magnitude and phase. The default is 0.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Response returns the complex number that this VI obtains by evaluating the system at Frequency (rad/s).
Magnitude returns the magnitude of Response in decibels.
Phase (deg) returns the phase in degrees of Response.
error out contains error information. This output provides standard error out functionality.
