Delta RMC151 - Manual (Page 245)

4 Using RMCTools
The System Identification tool calculates system models for the currently displayed plot. The
System Identification tool assigns a score to each model, with a lower number indicating a
better fit. This tool does not apply the calculated models to the axis. However, you can
manually enter these values in the axis' model parameters.
Use the Tuning Wizard to calculate a system model and apply the values to the axis
parameters. See the Modeling topic for details on how the system model is used.
ID a Portion of the Plot
The System Identification tool allows you to calculate a system model for only a portion of
the plot:
1. On the Plots menu, choose View, and click Show 2nd Cursor.
2. Use the mouse to drag the cursors to select the desired portion of the plot.
3. On the Plots menu, choose View, then click System Identification Tool.
To remove the second cursor, on the Plots menu, choose View, and click Hide 2nd
Cursor.
Advanced
Click View Log to view the calculation results. The log also shows the parameters
calculated for type 0 or type 1 systems, and zero, first, and second order models.
In a Type 0 system, the controlled variable is roughly proportional to the Control Output.
In a Type 1 system, the rate of the controlled variable is roughly proportional to the
Control Output.
