Analyze Batch Linearization Results in Linear Analysis

Tool

This example shows how to use response plots to analyze batch linearization results in

Linear Analysis Tool. The term batch linearization results refers to linearizations for

varying parameter values, such as illustrated in “Batch Linearize Model for Parameter

Value Variations Using Linear Analysis Tool” on page 3-75. You can use the techniques

illustrated in this example to analyze the frequency response, stability, and other system

characteristics for batch linearization results.

For this example, suppose that you have batch linearized a model as described in “Batch

Linearize Model for Parameter Value Variations Using Linear Analysis Tool” on page 3-

75. You have generated a step response plot of an array of linear models computed for a
    2-D parameter grid, with variations of outer-loop controller gains Ki1 and Kp1.

When you perform batch linearization, Linear Analysis Tool generates a plot showing the

responses of all linear models resulting from the linearization. You choose the response

plot type, such as Step, Bode, or Nyquist, when you linearize. You can create additional

plots at any time as described in “Analyze Results Using Linear Analysis Tool Response

Plots” on page 2-151.

To view the parameters associated with a particular response, click the response on the

plot.
