  • System and method for automatic tuning of reference model for fracking rig pump
    Patent number: 9945375
    Abstract: A method for automatic tuning of a reference model for a fracking rig pump is provided. The method includes determining, at a processor connected to a fracking rig pump, a current choke area associated with the fracking rig pump based upon at least a maximum power and a maximum pressure obtained from the fracking rig pump for a pump speed of the fracking rig pump, obtaining a pump power and a pump pressure for the current choke area based upon at least a reference model for the fracking rig pump stored in a memory device coupled to the processor, determining a pressure difference between the maximum pressure obtained from the fracking rig pump and the pump pressure, determining a power difference between the maximum power obtained from the fracking rig pump and the pump power obtained from the reference model, and providing an updated choke area to the reference model.
