Estimating the term…
A first drive acts on a machine element via a transmission and a second drive acts on the machine element directly. First and second closed-loop speed controllers determine respective first and second setpoint force values for the first and second drives with the aid of the difference between the setpoint speed value and of the actual speed value and activate the first drive and/or the second drive as a function of the respective first and second setpoint force values. Respective first and second pilot force values are determined from a first axis inertia scaled by a first scaling factor (α), and second axis inertia scaled by a second scaling factor (1−α).
A closed-loop controller structure, comprising:
A method for closed-loop control of a drive unit having a first drive operating on a machine element via a transmission facility and being controlled by a first pilot force value, and a second drive being controlled by a second pilot force value and operating directly on the machine element for movement of the machine element in relation to an axis, the method comprising:
