Dynamic System Models generally represent systems that have internal dynamics or memory of past states such as integrators, delays, transfer functions, and state-space models.
Most commands for analyzing linear systems, such as bode, margin,
and linearSystemAnalyzer, work on most Dynamic
System Model objects. For Generalized Models, analysis commands use
the current value of tunable parameters and the nominal value of uncertain
parameters. Commands that generate response plots display random samples
of uncertain models.
The following table lists the Dynamic System Models.
