ABSTRACT:
An earth moving or construction equipment implement control system is disclosed. The control system includes a fuzzy logic controller that is connected to an electro-hydraulic valve. An implement position sensing system senses the height of the implement. A set point is compared to the implement position to produce an implement position error signal which is an input to the fuzzy logic controller.
