Export Simulink Model as Standalone FMU

Generate co-simulation and model exchange FMU 2.0 or 3.0 from Simulink models

Export a Simulink model as a Functional Mockup Unit (FMU) compatible with FMI 2.0 or 3.0 standards. Set up the model with required interface, tunable parameters, internal variables, and enable cross-platform compilation and simulation. Use the FMU Builder wizard or command-line functions to define the FMU specifications. Generate FMUs for either co-simulation or model exchange. Customize the FMU package by specifying its contents to suit your deployment needs.

To import your existing FMUs into Simulink, see Import FMUs.

Observe Internal Variables to Tune PID Controller Inside an FMU

In this system, the PID controller calculates the force that needs to be exerted on the mass to control its position. The Observer blocks allow you to tune the PID controller by providing wireless access to the control input and tracking errors that are configured as internal variables.
