[CN202110351130.X] A Control Method and Control System Title of Servo Stretching Pad Based on Mechanical Press: A Control Method and Control System of Servo Stretching Pad Based on Mechanical Press Application Number: CN202110351130.X Applicant: Tianjin Yizhong Electric Automation Co., Ltd. Application Date: 2021-3-31 Patent Type: Application for the Invention The present invention discloses a control method and control system of servo stretching pad based on mechanical press, the whole process of motion control of the stretching pad is divided into five stages: pre-acceleration stage, pressure building stage, stretching to the bottom dead center stage, bottom dead center locking or sinking stage, and returning from the bottom dead center or sinking point to the reclaiming position or starting position stage, which can well solve the problem of different control accuracy of the stretching pad in the production of different products. The use of different control parameters of different formulations can make the control system not need to adapt to different products to take compromise parameters, but to set accurate control parameters for different products. In addition, for different control stages, the controller with different control parameters is selected to more accurately control the five stages of servo stretching pad stretching, which solves the problem that the control performance can not be optimized due to the traditional use of a set of control system parameters to adapt to the five different stretching stages.
