Tunable Generalized LTI models represent systems having both fixed and tunable (or parametric) coefficients. Use Control Design Blocks to represent tunable components of your control system. Combine them with Numeric LTI models to create tunable Generalized LTI models. For an example, see Control System with Tunable Components.
You can use tunable Generalized LTI models to:
Model a tunable (or parametric) component of a control system, such as a tunable low-pass filter.
Model a control system that contains both:
Fixed components, such as plant dynamics and sensor dynamics
Tunable components, such as filters and compensators
Tuning control systems to design goals you specify,
using tuning commands such as
systune or the
Control System Tuner app.

Represent a transfer function with a tunable parameter.
Represent a transfer function with multiple tunable parameters.
Represent state-space matrices that have a mix of fixed and tunable parameters.
Build a control-system model for tuning using both tunable and fixed components.
Build a control-system model with analysis points for extracting responses at different points in the system.
Generalized models represent systems having a mixture of fixed coefficients and tunable or uncertain coefficients.
Use tunable models to model tunable components of control systems for parameter sampling or control system tuning.
Analysis points allow you to access to internal signals, perform open-loop analysis, or specify requirements for controller tuning in systems modeled in either MATLAB® or Simulink®.
