[CN 201911153656.6] Non-linear pressure position control device and method for servo press


[CN 201911153656.6] A Nonlinear Pressure Position Control Device and Method for Servo Press Title: A Nonlinear Pressure Position Control Device and Method for Servo Press Application Number: CN 201911153656.6 Applicant: Shandong Academy of Sciences Laser Research Institute Application Date: 2019-11-22 Patent Type: Application for the Invention The embodiment of the present invention discloses a nonlinear pressure position control device and method for servo press, including. The control device includes a position controller, a speed selector, a pressure controller, a speed controller, and a speed transducer. The speed converter is respectively connected to the pressure controller and the speed selector, and the speed converter is used to convert the slider speed output by the pressure controller into the motor speed. The invention, in view of the nonlinear characteristics in the servo press transmission mechanism, uses a speed converter for nonlinear transformation, and solves the defects of unstable operation and low precision of the linear controller of the existing method.
