Robust Control Toolbox™ software provides an Uncertain State Space block to model parametric and dynamic uncertainty in Simulink®. The block library also contains a MultiPlot Graph block that you use with the Uncertain State Space block to plot and visualize Monte Carlo simulation responses.
To open the Robust Control Toolbox block library, type the following command at the MATLAB® prompt:
The block library opens, as shown in the following figure.
Alternatively, in a Simulink model window, click to launch to Library Browser. In the Library Browser, select Robust Control Toolbox.
