Abstract
A landfill well control system is disclosed which provides the ability to input a user selected set point to control a flow related variable at a landfill wellhead. A flow control actuator controls movement of a landfill gas (LFG) flow control valve. A sensor may be used for sensing the flow related variable. A controller is operably associated with the flow control actuator and the sensor. A user interface has a set selection for enabling a set point associated with the flow related variable, which is to be controlled by the system, to be input by the user. The controller operates to control the LFG flow control valve as needed to maintain the set point in an autopilot-like fashion.
