The movement of a machine element of a machine that can be driven via a shaft with the aid of a motor can be guided by specifying a setpoint guidance variable describing a desired movement process of the machine element for the actuation of the motor and determining an actual pilot variable and/or an actual guidance variable from the setpoint guidance variable by subjecting the setpoint guidance variable to a digital path model which simulates the dynamic behavior of the machine element and the motor. The digital path model is parameterized by the total moment of inertia and the poles and zeros of the transfer function of the mechanical system consisting of motor, shaft and machine element.

Method and device for guiding the movement of a movable machine element of a machine

A controller controls a plurality of drives of a lifting device, wherein the controller is configured to perform a kinematic transformation of spatial position and orientation coordinates of a body and controls the drives based on the kinematic transformation. The drives can be electric drives. At least six drives are provided and regulated, so that their number exceeds the number of spatial position and orientation coordinates of the body. The lifting device is thus overdetermined.

Controller for a lifting device, and method for operating same

A control device, a system and methods for optimizing and providing movement profiles, wherein the movement profiles serve for determining the movement of tools of a press and the movement of a receiving element for a workpiece of a transfer system, where transfer movement profiles are synchronized with one another via press movement profiles, the synchronization of the transfer movement profiles particularly occurs by chronologically shifting synchronization points via boundary conditions such that an offset of the press movement profiles can be determined via the synchronization, so that the workpiece can be processed as quickly as possible through the system.
