kindly tell me how to increase the transport delay and how can i update the buffer size parameter as per the warning it is coming

Warning: The specified buffer for 'A_3_Phase_Inverter_26_11_2013/3-phase PLL/Automatic Gain Control/FundA/Variable Transport Delay' was too small. During simulation, the buffer size was temporarily increased to 133120. In order to use Real-Time Workshop, you need to update the buffer size parameter

have u got his answer ??? if u have help me out

Hi @arunav ray,

The issue that you are facing is about the buffer size parameter, of the ‘Variable Transport Delay’ block located at the path: 'A_3_Phase_Inverter_26_11_2013/3-phase PLL/Automatic Gain Control/FundA/Variable Transport Delay'. This warning usually indicates that the number of data points needed to store the delayed signal during simulation are exceeding the buffer size specified by the ‘Variable Transport Delay’ block. To resolve this, open the ‘Block Parameters’ dialogue for the ‘Transport Delay block’ and increase the 'Initial buffer size' parameter to a larger value.

Please refer to the following MathWorks documentation link to understand more about the ‘Initial Buffer Size’ parameter for transport delay blocks: https://www.mathworks.com/help/releases/R2024a/simulink/slref/transportdelay.html

I hope this helps.
