Claim 20:
21. The hydraulic fracturing control assembly of claim 20, wherein:
the one or more operational parameters associated with pumping fracturing fluid into a wellhead comprises a target pressure for fracturing fluid supplied to the wellhead; and
when it has been determined that the target pressure has not been achieved, the supervisory controller is further configured to:
determine whether a maximum total flow rate has been achieved; and
one of:
when the maximum total flow rate has been achieved, maintain the maximum total flow rate; or
when the maximum total flow rate has not been achieved, one or more of:
increase flow rates of the at least some hydraulic fracturing units to achieve the maximum total flow rate; or
maintain a fluid pressure at the wellhead within a pressure differential of the fluid pressure by one of increasing the total flow rate to increase the fluid pressure at the wellhead to be within the pressure differential or decreasing the total flow rate to decrease the fluid pressure at the wellhead to be within the pressure differential.
