Hi there,
I am using "" example for PMSM autotuning simulation. but i want to modify it as per my requirement, for that i remove autotuner for speed loop and include "closed loop PID autotuner" but it shows following error.
so, what is possible solution for the same?
i tried to edit block(closed loop PID autotuner), but unable to do so.

Based on the information you provided, replacing the 'FOC Autotuner' block with a 'Closed-Loop PID Autotuner' block is feasible. The error message you posted indicates possible sample-time mismatch associated with the inserted 'Closed-Loop PID Autotuner' block. To view sample times used in the model, please refer to the following link:
To resolve the issue, you will need to use 'Rate Transition' blocks to interface blocks with different sample times.Please also note that the 'Current Control' subsystem is a triggered subsystem, which is different from a block with fixed sample time. This triggering settings are because of its synchronization with ADC interrupt (explained in Sample time settings also need to be adjusted accordingly.
