Early warning method and device for feedback control system change, equipment and medium

The invention discloses an early warning method and device for feedback control system change, equipment and a medium. The method comprises the steps that in the process of executing real-time feedback control on a target feedback control system, a real-time feedback control track set matched with the target feedback control system is acquired; generating a real-time environment feature vector corresponding to the real-time feedback control track set by using a pre-trained feedback control system identifier, and calculating a difference value between the real-time environment feature vector and a reference environment feature vector of the target feedback control system; and when the difference value is greater than a set threshold value, performing feedback control system change early warning on the target feedback control system. By adopting the technical scheme, the change of the feedback control system can be quickly identified in the feedback control system based on the feedback control system identifier
