View and Change Block Parameterization in Control
System Tuner
Control System Tuner parameterizes every block that you designate for tuning.- When you tune a Simulink model, Control System Tuner automatically assigns a
default parameterization to tunable blocks in the model. The default parameterization
depends on the type of block. For example, a PID Controller block configured for PI
structure is parameterized by proportional gain and integral gain as follows:
u=Kp+Ki^1
s.
Kp and Ki are the tunable parameters whose values are optimized to satisfy your
specified tuning goals.- When you tune a predefined control architecture or a MATLAB (generalized state-
space) model, you define the parameterization of each tunable block when you create
it at the MATLAB command line. For example, you can use tunablePID to create a
tunable PID block.
Control System Tuner lets you view and change the parameterization of any block to be
tuned. Changing the parameterization can include changing the structure or current
parameter values. You can also designate individual block parameters fixed (non-tunable)
or limit their tuning range.View Block Parameterization
To access the parameterization of a block that you have designated as a tuned block, in
the Data Browser, in the Tuned Blocks area, double-click the name of a block. The
Tuned Block Editor dialog box opens, displaying the current block parameterization.10 Control System Tuning
