<p>A hydraulic control system (50) for a machine (10) is disclosed. The hydraulic control system (50) includes a pump (58) configured to pressurize a fluid, and a swing motor (49) selectively driven by pressurized fluid from the pump (58). The swing motor (49) is configured to move a part of the machine (10). The hydraulic control system (50) also includes a controller (100) in communication with the pump (58). The controller (100) is configured to receive an input indicative of a difference between a desired speed and an actual speed of the swing motor (49), and determine if the swing motor (49) is accelerating, decelerating, or operating at neutral mode. The controller (100) is configured to determine an amount of return fluid from an actuator of the machine (10) that is available as makeup fluid for the swing motor (49) if the swing motor (49) is operating at neutral mode. The controller (100) is configured to control the pump (58) based on at least the amount of return fluid.</p> |
