About Control Architecture
Control System Tuner lets you tune a control system having any architecture. Control
system architecture defines how your controllers interact with the system under control.
The architecture comprises the tunable control elements of your system, additional filter
and sensor components, the system under control, and the interconnections among all
these elements. For example, a common control system architecture is the single-loop
feedback configuration of the following illustration:
G is the plant model, and H the sensor dynamics. These are usually the fixed components
of the control system. The prefilter F and feedback controller C are the tunable elements.
Because control systems are so conveniently expressed in this block diagram form, these
elements are referred to as fixed blocks and tunable blocks.
Control System Tuner gives you several ways to define your control system architecture:
- Use the predefined feedback structure of the illustration.
- Model any control system architecture in MATLAB by building a generalized state-
space (genss) model from fixed LTI components and tunable control design blocks. - Model your control system in Simulink and specify the blocks to tune in Control
System Tuner (requires Simulink Control Design software).
Predefined Feedback Architecture
If your control system has the single-loop feedback configuration of the following
illustration, use the predefined feedback structure built into Control System Tuner.
