Simulation of a Fuel Cell Hybrid Vehicle ( Fuel Cell + Battery only )

Hi folks,

Can any one help me in buiding the model of Fuel Cell Hybrid Vehicle. One model is already here but not running on version R2024b. Error message is regarding missing libraries. The exact errors are mentioned below:

Error in 'power_FCV_powertrain/Energy Management Subsystem': Failed to evaluate mask initialization commands.

Caused by:

Unrecognized function or variable 'spsdrivelogo'.

Variable 'spsdrivelogo' does not exist.

Suggested Actions

Load a file into base workspace.

Fix

Create a new variable.

Fix

Component:Simulink | Category:Model error

Failed to load library 'DC6DriveInternalModels' referenced by 'power_FCV_powertrain/FCV Electrical Subsystem/DC-DC converter/DC//DC converter/Chopper'.

Component:Simulink | Category:Model error

Error in 'power_FCV_powertrain/FCV Electrical Subsystem/PM Synchronous Motor Drive This block is based on the AC6 drive block/Speed Controller': Failed to evaluate mask initialization commands.

Caused by:

Unrecognized function or variable 'spsdrivelogo'.

Variable 'spsdrivelogo' does not exist.

Suggested Actions

Load a file into base workspace.

Fix

Create a new variable.

Hi Bhasker,

The errors you are encountering while attempting to run the Fuel Cell Hybrid Vehicle (FCV) model in MATLAB/Simulink version R2024b are caused by missing libraries and variables.

• Ensure that the required toolboxes for this model are installed and compatible with R2024b. You can use the below command to check the toolboxes required for the model.

license('inuse') 

• The errors indicate that the "DC6DriveInternalModels" and "AC6DriveInternalModels" libraries are referenced in the model but cannot be found.

You can refer the below documentation links on:

Thanks for a quick reply Mr. Kothuri.

However, I have resolved the missing parts in the simulink block error. There were total 6 errors at the begining, now only three. All these three indicating to a missing .mat or .m file name having 'spsdrivelogo' as some variable name.

In old matlab versions 2018, it is running properly but not running in my machine. I am using R2024b. Also checked in R2025a Pre Release Version.

Facing disadvantage of using latest version.

Hi Bhasker ,

how did you find those files

[Bhasker]

I found simular simulink blocks used in some other models but still there were some errors like "missing variables" which are still there. I am unable to run this model on MATLAB R2024b.
