[CN 202111471485.9] A Method for Controlling Slider Position and Estimating Slider Pressure of a Servo Press Title: A Method for Controlling Slider Position and Estimating Slider Pressure of a Servo Press Application Number: CN 202111471485.9 Applicant: Jining Keli Optoelectronic Industry Co., Ltd. Application Date: 2021-12-6 Patent Type: Invention Application This invention belongs to the technical field of servo presses, and specifically relates to a method for controlling slider position and estimating pressure of servo presses. The invention directly estimates the slider pressure of the servo press through the control algorithm, and adds the calculation of the motor load torque estimation value to the given value in the servo motor control algorithm, which greatly improves the torque following situation and the motor response speed when the servo press system suddenly encounters a large load and the workpiece is pressurized, so that the process curve following performance in the forming process is greatly improved.
