Abstract: A control system for a work machine includes a non-contact sensor, a position output device, a correction position calculation unit, and a control device. The non-contact sensor detects a periphery of a work machine. The position output device determines a position of the work machine based on at least a detection result of the non-contact sensor, and outputs information of the position. The correction position calculation unit corrects the position determined by the position output device based on delay time including at least a delay in communication with the position output device. The control device generates a command for controlling the work machine using the corrected position corrected by the correction position calculation unit.
