Example 3: Frequency response analysis with a mass-spring damper system

This section introduces Frequency Response Analysis through a mass-spring damper system example.

Bode, Nichols and Nyquist plots

Bode, Nichols and Nyquist plots are the most commonly used tools for frequency response. You need at least one control variable and at least one observer variable. You must of course do a linearization and it should be at an equilibrium point.

Nyquist plot

Note

Plot update and plot configurations are now supported with Frequency response plots.

We will use the system shown in figure Figure 90.
