[CN 201910421580.4] A Multi-point Nonlinear Predictive Control System for Press
[CN 201910421580.4] Title of a multi-point nonlinear predictive control system for a press: Application number of a multi-point nonlinear predictive control system for a press: CN 201910421580.4 Applicant: Laser Research Institute of Shandong Academy of Sciences Application Date: 2019-5-21 Patent Type: Invention Application The present invention belongs to the technical field, and specifically relates to a multi-point nonlinear predictive control system for a press. The present invention measures the stroke position near different force application points of the slider through a nonlinear servo control method, the motor speed and torque corresponding to different force application points are controlled respectively, so as to ensure that the stroke positions at different force application points of the slider are equal, the synchronous control and nonlinear control of the multi-point press are realized, the defect of mechanical vibration is eliminated, and the problem of the plane skew of the slider caused by the excessive pressure offset of the mechanical coupling multi-point synchronous control is eliminated.
