To create a Simulink® model, you add blocks to a block diagram, and then connect and configure those blocks. You can assign values to numeric block parameters, which control block calculations during simulation, and adjust block properties, which control appearance.
Adjust the parameters and properties of blocks to:
Experiment with parameter values as you design a model.
Match simulation results with measured data by estimating parameter values.
Design an efficient control algorithm by optimizing parameter values.
Document blocks and customize appearance.
Define system constants by creating global variables that you can share between blocks and models.
Blocks have numeric parameters that determine how they calculate output values. To control the calculations that blocks perform, you can specify parameter values.
To set multiple block parameters to the same value, you can use a numeric variable that you create and store in a workspace such as the base workspace, a model workspace, or a data dictionary.
Design one model for many systems that differ in block parameter values.
For each block parameter in a reusable component, specify the same value for all instances of the component or a different value for each instance.
Increase model readability and reduce the effort of model maintenance by aggregating block parameter values into structures.
As you construct a model you can experiment with block parameters, such as the coefficients of a Transfer Fcn block, to help you decide which blocks to use.
Use parameter sweeping to tune control parameters, estimate unknown model parameters, and test the robustness of a control algorithm by taking into consideration uncertainty in the real-world system.
Switch between independent sets of values for the same block parameters by storing the sets in an array of structures.
Control the data type that Simulink and the generated code use to store block parameter values in computer memory.
Fully specify your design and optimize the generated code by setting minimum and maximum values for numeric block parameters.
To write scripts that create and modify models, determine the programmatic name of a parameter or property in a block dialog box.
