A control system for a machine having a power source configured to provide power, a number of implements including a work implement, configured to provide operations, and a number of power transmitting paths configurable to selectively make power available to the implements to perform operations. The control system may include a control arrangement configured to regulate the power source to provide a first level of available power, to configure a first power transmitting path to make a percentage Aof said first level of power available to provide a first operation, and to configure a second power transmitting path to make a percentage Aof said first level of power available to provide a second operation, at least the second operation being a work operation. The control arrangement may further be configured to increase said first level of available power of said power source to a second level of available power, to configure the first power transmitting path to make a percentage Bof said second level op power available to provide said first operation, and to configure the second power transmitting path to make a percentage Bof said second level of power available to provide said second operation, such that the ratio B/Bis greater than the ratio A/A

Machine power control with ratio increase

A method of controlling a machine having a hydraulically actuated linkage includes lowering a load suspended by the leakage at least in part by leaking hydraulic fluid from a portion of a hydraulic actuation system, and generating a drift compensation control signal responsive to leaking hydraulic fluid. A machine includes an electronic controller in control communication with a valve, the electronic controller being configured to compensate for leakage induced drift of at least one hydraulic actuator of a machine hydraulic system by selectively commanding adjusting of the valve if drift criteria for the hydraulic system are satisfied.
