FMI Module
Get the best of PSIM and FMI supporting software.
The FMI Module provides the capability to generate FMU (functional mock-up unit) models in PSIM and perform co-simulation with other software that supports the FMI standard. Exporting FMU models in PSIM is straightforward and easy to set up, and requires minimal user input.
With this Module, part of a system can be implemented and simulated in PSIM and the rest in the other software. With FMI, there’s no need to choose between the tools, and you can make best use of PSIM and the other software in a complementary way in your next project.
Easily Exportable FMU Models
Generate easily exportable FMU models with just a few clicks. The generated FMU models can be loaded by other software that supports the FMI standard for co-simulation.
The list of FMI Supporting Tools is long and includes most major design and simulation tools.
Co-simulation with 60+ other software tools
Easyly set-up co-simulation with minimum user input
Generation of easily exportable FMU models
Waveform display in both PSIM and FMI supporting software
Application Example: Power converter stage in PSIM exported to Simulink
Power stage in PSIM
This example shows the power stage of a current-controlled buck dc-dc converter in PSIM ready to be exported to a FMU model. For the control stage, we are using Matlab/Simulink as the other software to load the FMU model generated by PSIM and perform co-simulation.
Control stage in Simulink
The control loop with PI controller is implemented in Simulink, as shown below. In the control loop, the inductor current is measured and compared with a reference. The error signal is sent to a PI controller, and the PI output is compared with a carrier waveform to generate the gating signal for the switch. In this way, the FMI Module allows us to simulate control in MATLAB/Simulink while simulate the power stage in PSIM.
