  • Automated neuro-fuzzy drive control system for the construction 3D printer's screw doser printhead

    The problem of synthesizing the parameters of the drive control system of the responsible unit of the construction 3D printer - the screw dispenser of the print head using the method of neuro-fuzzy control is considered. An algorithm for building an intelligent drive control system is described. A training sample is obtained from the data of variables determined as a result of modeling the automatic system control with a continuous proportional-integral-differentiating (PID) regulator. Training of a neuro-fuzzy output system in the MATLAB software environment is performed using the hybrid method a. Transient characteristics of the control system with continuous and neuro-fuzzy proportional-differentiating (PD) regulator are obtained. Direct indicators of the quality of the considered control systems are determined, and an analysis of these results is carried out. The use of neuro-fuzzy control of the screw doser drive of the 3D printer print head made it possible to obtain the desired a transient process confirmed as a result of a computational experiment.
