A control system for controlling a work machine equipped with a work implement that comprises a plurality of elements and with a plurality of actuators that drive the plurality of elements, said control system comprising: a first hydraulic pump and a second hydraulic pump that supply hydraulic fluid to at least one of the plurality of actuators; and a control device that calculates the distribution flow rate of the hydraulic fluid distributed to the respective actuators on the basis of the operating state of the work implement, and switches, on the basis of the obtained distribution flow rate,between a first state, in which the hydraulic fluid supplied from both the first hydraulic pump and the second hydraulic pump is supplied to the plurality of actuators, and a second state, in which the one or more actuators supplied the hydraulic fluid from the first hydraulic pump differ from the one or more actuators supplied the hydraulic fluid from the second hydraulic pump.
