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 an operation of a mechanism is provided. A first rate limit is assigned to a first input device that is operable to generate a first signal to control the operation of the mechanism. A second rate limit is assigned to a second input device that is operable to generate a second signal to control the operation of the mechanism. At least one of the first and second input devices are manipulated to effect a desired change in the operation of the mechanism. A maximum allowable rate of change in the operation of the mechanism is identified based on the first and second signals and the first and second rate limits. A rate of change in the operation of the mechanism to achieve the desired change in the operation of the mechanism is determined based on a comparison of the maximum allowable rate of change in the operation of the mechanism with a last used rate of change in the operation of the mechanism.
