memory comprising instructions; and

at least one processor to execute the instructions to cause the system to:

estimate, in a testing environment, values to be associated with parameters associated with vibrations in the system, the vibrations measured using oscillation alarms;

determine a subset of the parameters based in part on their respective values causing the vibrations to be maintained below a threshold, the threshold to be set using the oscillation alarms; and

enable an encoderless vector control subsystem to receive electric power from a power source and to control an electric motor for the fracturing operations, based at least in part on the subset of the parameters.
