Cascaded Multiloop Feedback Design

This example shows how to tune two cascaded feedback loops in Simulink® Control

Design™ using Control System Designer.

This example designs controllers for two cascaded feedback loops in an airframe model

such that the acceleration component (az) tracks reference signals with a maximum rise

time of 0.5 seconds. The feedback loop structure in this example uses the body rate (q) as

an inner feedback loop and the acceleration (az) as an outer feedback loop.

Open the airframe model.

open_system('scdairframectrl')

The two feedback controllers are:

• scdairframectrl/q Control - A discrete-time integrator and a gain block stabilize
  the inner loop.
