In many cases, these oscillations can be treated as quantization noise (Widrow and Kollár, 2008), and can be handled elegantly with the corresponding quantization theory. However, we are interested in the structure and patters of quantization in case of a digitally controlled inverted pendulum with input and output quantizers and sampling. We show the patterns of control effort in case of a simple PD control and highlight how these patterns – along with the dynamics of the controlled system – lead to attractors or periodic cycles with superimposed chaotic oscillations.}, year = {2018}, eissn = {2405-8963}, pages = {256-261}, orcid-numbers = {Gyebrószki, Gergely/0000-0002-0263-7510; Csernák, Gábor/0000-0001-9559-761X} } @article{MTMT:3398967, title = {Stability of turning processes for periodic chip formation}, url = {https://m2.mtmt.hu/api/publication/3398967}, author = {Gyebrószki, Gergely and Bachrathy, Dániel and Csernák, Gábor and Stépán, Gábor}, doi = {10.1007/s40436-018-0229-6}, journal-iso = {ADV MANUF}, journal = {ADVANCES IN MANUFACTURING}, volume = {6}, unique-id = {3398967}, issn = {2095-3127}, abstract = {The prediction of chatter vibration is influenced by many known complex phenomena and is uncertain. We present a new effect that can significantly change the stability properties of cutting processes. It is shown that the microscopic environment of chip formation can have a large effect on its macroscopic properties. In this work, a combined model of the surface regeneration effect and chip formation is used to predict the stability of turning processes. In a chip segmentation sub-model, the primary shear zone is described with a corresponding material model along layers together with the thermodynamic behavior. The surface regeneration is modeled by the time-delayed differential equation. Numerical simulations show that the time scale of a chip segmentation model is significantly smaller than the time scale of the turning process; therefore, averaging methods can be used. Chip segmentation can decrease the average shear force leading to decreased cutting coefficients because of the non- linear effects. A proper linearization of the equation of motion leads to an improved description of the cutting coefficients. It is shown that chip segmentation may significantly increase the stable domains in the stability charts; furthermore, by selecting proper parameters, unbounded stability domains can be reached.}, year = {2018}, eissn = {2195-3597}, pages = {345-353}, orcid-numbers = {Gyebrószki, Gergely/0000-0002-0263-7510; Bachrathy, Dániel/0000-0003-1491-1852; Csernák, Gábor/0000-0001-9559-761X; Stépán, Gábor/0000-0003-0309-2409} } @{MTMT:3256628, title = {Effect of periodic chip formation on the stability of turning processes}, url = {https://m2.mtmt.hu/api/publication/3256628}, author = {Gyebrószki, Gergely and Bachrathy, Dániel and Csernák, Gábor and Stépán, Gábor}, booktitle = {Proceedings of the 9th European Nonlinear Dynamics Conference, ENOC 2017}, unique-id = {3256628}, year = {2017}, orcid-numbers = {Gyebrószki, Gergely/0000-0002-0263-7510; Bachrathy, Dániel/0000-0003-1491-1852; Csernák, Gábor/0000-0001-9559-761X; Stépán, Gábor/0000-0003-0309-2409} } @inproceedings{MTMT:3256626, title = {Inherent control error in a multi-PD controlled double inverted pendulum}, url = {https://m2.mtmt.hu/api/publication/3256626}, author = {Gyebrószki, Gergely and Csernák, Gábor}, booktitle = {Proceedings of the 9th European Nonlinear Dynamics Conference, ENOC 2017}, unique-id = {3256626}, year = {2017}, orcid-numbers = {Gyebrószki, Gergely/0000-0002-0263-7510; Csernák, Gábor/0000-0001-9559-761X} }
