In a control system, a controller is configured to determine presence or absence of an obstructed area within the intermediate section, and control movement of the moving body in accordance with a selected one of controlling methods including a first and a second control methods. The first control method causes the moving body to move at a first constant speed in the processing section defined within the intermediate section and at a second constant speed faster than the first constant speed in at least a part of a non-processing section within the intermediate section and other than the processing section, the first control method being selected when the obstructed area is absent. The second control method causes the moving body to move at the first constant speed in the processing section and the non-processing section, the second control method being selected when the obstructed area is present.
