What Blocks Are Tunable?

You can tune parameters in the following Simulink^® blocks using Simulink Control Design™ software. The block input and output signals for tunable blocks must have scalar, double-precision values.

Tunable Block	Description
Gain	Constant gain
LTI System	Linear time-invariant system
Discrete Filter	Discrete-time infinite impulse response filter
PID Controller	One-degree-of-freedom PID controller
Discrete PID Controller	Discrete-time one-degree-of-freedom PID controller
State-Space	Continuous-time state-space model
Discrete State-Space	Discrete-time state-space model
Zero-Pole	Continuous-time zero-pole-gain transfer function
Discrete Zero-Pole	Discrete-time zero-pole-gain transfer function
Transfer Fcn	Continuous-time transfer function model
Discrete Transfer Fcn	Discrete-time transfer function model

Additionally, you can tune the linear State-Space, Zero-Pole, and Transfer Fcn blocks in the Simulink Extras Additional Linear library.

You can tune the following versions of the listed tunable blocks:

• Blocks with custom configuration functions associated with a masked subsystem

• Blocks discretized using the Simulink Model Discretizer

Note

If your model contains Model blocks with normal-mode model references to other models, you can select tunable blocks in the referenced models for compensator design.
