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

A method for guiding the movement of a movable machine element of a machine, comprising the steps of:

• a) inputting a travel movement to be carried out by a machine element, and an optimization criterion;
• b) determining a movement profile in response to the travel movement and the optimization criterion by selecting an optimization method as a function of the optimization criterion and determining the movement profile with the selected optimization method;
• c) determining a setpoint variable by means of the movement profile;
• and
• d) outputting the setpoint variable to a closed-loop controller for executing the travel movement of the machine element.

A control device for guiding the movement of a movable machine element of a machine, comprising:

• first means for inputting a travel movement to be carried out by the machine element and an optimization criterion;
• second means for determining a movement profile on the basis of the travel movement and the optimization criterion by selecting an optimization method as a function of the optimization criterion and determining the movement profile with the selected optimization method;
• and
• third means for determining a setpoint variable on the basis of the movement profile and outputting the setpoint variable to a closed-loop controller for executing the travel movement of the machine element.

A system for guiding the movement of a movable machine element of a machine, comprising:

• an input unit for allowing a user to input data relating to a travel movement to be carried out by a machine element and to input an optimization criterion;
• a calculation unit responsive to the data for establishing a movement profile on the basis of an optimization method;
• a device for generating a setpoint variable on the basis of the movement profile;
• and
• a closed-loop controller for instructing a drive to execute the travel movement of the machine element in response to the setpoint variable.
