The invention discloses a yaw stability control system for an automatic guided vehicle. The yaw stability control system comprises an upper-layer controller and a lower-layer controller electrically connected with the upper-layer controller, wherein the upper-layer controller comprises a yaw velocity controller, a side slip angle controller, an extension combined controller and a sliding mode controller which are electrically connected with the automatic guided vehicle; the sliding mode controller is connected with the yaw velocity controller, the side slip angle controller and the extension combined controller; the lower-layer controller is a driving torque distribution controller and is electrically connected with a hub motor of the automatic guided vehicle. According to the invention, yaw stability of the automatic guided vehicle under the working condition of variable centroid is greatly improved.
