Abstract
A control system for a machine having a power source, a traction device, and a ripping tool is disclosed. The control system may have a slip sensor configured to generate at least one signal indicative of machine slippage, and at least one actuator operable to position the ripping tool. The control system may also have a controller in communication with the slip sensor, the at least one actuator, and the power source. The controller may be configured to receive at least one operator input indicative of an acceptable slip value, and determine actual machine slippage based on the at least one signal. The controller may also be configured to directly and separately regulate a speed of the machine and a position of the ripping tool during an excavation process based on the acceptable slip value and actual machine slippage.
