In the state of the art, the preload torque is commonly set to a constant value during commissioning. This poses a conflict of objectives between maximizing performance and minimizing energy consumption. To resolve this, this publication presents a novel approach to automatically adapt the preload torque during operation. For this purpose, the established preload control is extended by a simple control law that adapts the preload torque to the current operating state within the permissible limits. This way, higher preload torques are only applied, if the resulting higher system stiffness is beneficial for the drive performance. Otherwise, the preload torque is reduced to save energy. The automatic preload adaptation is experimentally validated on a test system with industry standard components. This involves both system-theoretical analyses and practical test scenarios.", "issn" : "1863-7353", "doi" : "10.1007/s11740-024-01318-7", "bibtexKey": "Steinle2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/248571bf42f9b3e1b94b541f568cd4f0f/isw-bibliothek", "tags" : [ "compensation","drive","error","feed","isw","learning","machine","tool" ], "intraHash" : "48571bf42f9b3e1b94b541f568cd4f0f", "interHash" : "fc115f1ff8efe474a50ffb3153d44a85", "label" : "Learning Compensation of the State-Dependent Transmission Errors in Rack-and-Pinion Drives", "user" : "isw-bibliothek", "description" : "", "date" : "2024-07-26 11:59:23", "changeDate" : "2024-07-26 12:00:17", "count" : 1, "pub-type": "inproceedings", "booktitle": "2024 European Control Conference (ECC)", "year": "2024", "url": "", "author": [ "Lukas Steinle","Valentin Leipe","Armin Lechler","Alexander Veri" ], "authors": [ {"first" : "Lukas", "last" : "Steinle"}, {"first" : "Valentin", "last" : "Leipe"}, {"first" : "Armin", "last" : "Lechler"}, {"first" : "Alexander", "last" : "Veri"} ], "pages": "2441-2447","abstract": "Rack-and-pinion drives are commonly used in large machine tools to provide linear motion of heavy loads over long travel distances.

To address this issue, this paper presents a method for robust modeling of the individual and state-dependent transmission errors of a drive utilizing a two-stage machine learning approach. Based on this, the position control is extended to include an error compensation, which suppresses the modeled deviations in the mechanical system including the position-dependent backlash.

Each of those strategies resulted in numerous improvements, however, they still lack reciprocal consideration.To overcome this deficit, a machine-independent energy control system to include any control- or operation-based energy optimizer will be introduced in this paper. It is based on real-time control information from the machine and software-based energy demand optimizers targeting the machining process, the machine tool components control as well as the overlaying production process. The control system itself ensures the correct cooperative operation of the three optimizer types, to enable the much needed reciprocal consideration of the optimizers effects. 2015 The Authors.
