create ai-based reduced order models

simulink add-on for reduced order modeling provides an app for creating reduced order models (roms) of subsystems modeled in simulink, including full-order, high-fidelity third-party simulation models. you can use reduced order models for system-level desktop simulation, hardware-in-the-loop (hil) testing, control design, and virtual sensor modeling.

with simulink add-on for reduced order modeling, you can:

set up the design of experiments and generate input-output training data from a full-order, high-fidelity subsystem
train and compare ai-based reduced order models using pre-configured templates
export ai-based surrogate models to simulink for system-level simulation, control design, and hil testing
export reduced order models as functional mockup units (fmus) for use outside of matlab and simulink (with simulink compiler)

design experiments

select simulink signals and block parameters to use as rom inputs, outputs, and parameters. interactively design simulation experiments by selecting from built-in excitation types to replace or perturb rom inputs. visualize coverage of design space.

run experiments

specify the option to run experiments one at a time or in parallel with parallel computing toolbox and initiate model simulations. visualize simulation results for signals and parameters of interest using built-in visualization plots.

train reduced order models

train and compare different types of reduced order models. choose from neural state space, lstm, and nonlinear arx models. optimize hyperparameters sequentially or in parallel with parallel computing toolbox to improve model fit. compare accuracy metrics for trained models to select the optimal one for your application.

use reduced order models in simulink

bring trained roms into simulink for system level simulation, control design, and hil testing. combine roms with first principles-based component models.

deploy and export reduced order models

deploy roms to embedded systems through automatic code generation. export roms as fmus (with simulink compiler) for use outside of matlab and simulink.
