HYDRAULIC CONTROL SYSTEM HAVING CYLINDER STALL STRATEGY

摘要

A hydraulic control system (48) for a machine (10) is disclosed. The hydraulic control system may have a hydraulic circuit (50), a pump (52) configured to supply pressurized fluid, and a first sensor (105) configured to generate a first signal indicative of a pressure of the hydraulic circuit. The hydraulic circuit may also have a first fluid actuator (20) fluidly connected to receive pressurized fluid from the hydraulic circuit, a second sensor (103) configured to generate a second signal indicative of a velocity of the first fluid actuator, and a controller (58) in communication with the first and second sensors. The controller may be configured to receive an input indicative of a desired flow rate for the first fluid actuator, to determine an actual flow rate of the first fluid actuator based on the second signal, and to determine a stall condition of the first fluid actuator based on the desired flow rate, the actual flow rate, and the first signal.
