Abstract

The invention relates to a processing process adaptive control method based on digital twinning. The method comprises the steps of constructing an instinct reaction mechanism in the manufacturing process of a digital twin processing system based on biological characteristics; real-timely detecting the signals in the manufacturing process of the digital twin processing system, and recognizing an abnormal signal through a neural network model; when the abnormal signal is recognized, generating a control action corresponding to the recognized abnormal signal according to the instinct reaction mechanism, and enabling the digital twin processing system to make a stress reaction according to the control action; based on the control action, determining a behavior anomaly type by adopting a graph structure algorithm; generating a control strategy according to the abnormal behavior type, so that the purposes that a machine is endowed with a human reaction thinking model, a system can sense variables and conduct corresponding control operation, are achieved, then real-time control is conducted on machining process states of different types and different conditions through a biological behavior mechanism, and the control efficiency and accuracy are improved.
