Abstract
A method of controlling a pumping stage of a fracturing fleet at a wellsite with a set of diesel pumps and at least one electric pump to smooth the flowrate transition to an operational setpoint with a higher flowrate. An optimization process communicatively connected to the plurality of pumping units can iterate an interim setpoint with a transfer function model to each pumping unit. The transfer function model can generate a smooth flowrate transition by decreasing the flowrate of at least one pump unit while increasing the flowrate to the remaining pump units.
