Dear Team,

While trying to open the below model (Digital DC/DC Buck Converter Using Peak Current Mode Control) and trying to deploy in LAUNCHXL-F28379D getting the below error from CLA Block.

link: openExample('texasinstrumentsc2000/PeakCurrentModeControlExample')

Error:

"C:/Users/Pratyay/Documents/MATLAB/Examples/R2021a/texasinstrumentsc2000/PeakCurrentModeControlExample/DCDC_Buck_PCMC_matlab_ert_rtw/cla_task.cla", line 41: error: identifier "DCDC_Buck_PCMC_matlab_P" is undefined 1 error detected in the compilation of "C:/Users/Pratyay/Documents/MATLAB/Examples/R2021a/texasinstrumentsc2000/PeakCurrentModeControlExample/DCDC_Buck_PCMC_matlab_ert_rtw/cla_task.cla". >> Compilation failure

Please provide if there any solution for this.

Thanks,

Pratyay

Hi Pratyay,

As per my knowledge f28379D Launchpad is used for voltage-mode control. If you want to implement peak current-mode control then Simulink has f280049C Launchpad for the sole purpose of operating DCDC Buck in PCMC mode. To open it go to MATLAB command window and enter f280049C_DCDC_Buck_PCMC. Currently in R2022a it supports code-gen variant but it will serve your purpose.
