Claim 12:
13. A method of controlling a pumping sequence of a fracturing fleet at a wellsite, comprising:
receiving, by a global control process executing on a computer system, an operating setpoint for a current stage of a designed pumping procedure, wherein the operating setpoint comprises a target pressure, and wherein the designed pumping procedure comprises a plurality of sequential pumping stages;
directing, by the global control process, a pumping operation of a plurality of pump units comprising at least two electric frac pumps by transmitting a first unit setpoint to each of the pump units, wherein the first unit setpoint is the operating setpoint, and wherein the plurality of pump units are communicatively connected to the computer system;
determining a wellbore pressure change; and
maintaining, by the global control process, the target pressure of the pumping operating by communicating a second unit setpoint to at least one electric frac pump in response to the wellbore pressure change.
