Under voltage error occurred while estimating PMSM parameters using TI LaunchPad 28379D and Boost pack 8305

While performing the same in 2023a I got the serial communication error. Then I've installed 2023b and the simulation was performed. I received Undervoltage error. This is the error message.

Error:An error occurred while running the simulation and the simulation was terminated

Caused by:

Under-voltage detected.

Error in 'mcb_param_est_host_read/Algorithm/SignalConditioning/ErrorConditions' (line 23)

(error(message('mcb:blocks:UnderVoltageDetected')));

Hi Saathwik, I can understand that encountering an under-voltage error while estimating PMSM parameters using the TI LaunchPad 28379D and Boost pack 8305, especially after updating from MATLAB 2023a to 2023b.

The error message indicating an under-voltage condition suggests that the system is not receiving sufficient voltage to perform the desired operations, which is often related to the power supply setup.

To address this issue, consider the following steps:

• Ensure Proper Power Supply Connection: Verify that the 24V DC power supply is correctly connected to the inverter board. Check all connections for any loose wires or poor contacts.
• Activate the Power Supply Before Simulation: Confirm that the power supply is turned on and providing a stable output before starting the simulation. This ensures that the inverter board is powered throughout the simulation process.

Following these steps should help resolve the under-voltage error.
