Claim 18:
19. The hydraulic fracturing system of claim 18, wherein the supervisory controller is configured to one or more of:
change the maximum rate of change of the flow rate as the total flow rate increases to achieve the one or more of the target flow rate or the target pressure to determine the maximum rate of change of the flow rate; or
the one or more sensors include one or more wellhead sensors configured to generate one or more signals indicative of one or more of fluid flow rate or fluid pressure at the wellhead, and the supervisory controller is configured to:
receive one or more signals indicative one or more of fluid flow rate or fluid pressure at the wellhead; and
determine the maximum rate of change of the flow rate based at least in part on the one or more signals indicative of one or more of the fluid flow rate of fluid pressure at the wellhead.
