The utility model relates to a door and window closing control system based on electromagnetic damping, including permanent magnet, electro -magnet, speedtransmitter, damping unit and power, permanentmagnet and electro -magnet set up respectively in door and window inside casing and frame, and just to distributing, speedtransmitter is used for measurement of inductance door and window's translation rate and produces corresponding output signal, power, damping unit and it forms closed -loop to connect in proper order between the electro -magnet, the power is used for providing the electro -magnet electric current, the damping unit is received speedtransmitter's output signal and switching according to output signal gets into the the direction of current flow of electro -magnet. The utilitymodel discloses an actively the effect lies in utilizing magnet like poles repel opposite poles attract's principle, reduces user's noise that the framework collision produced when closed door and window, has prevented the da
