On 3 November 2020, LMS presented the conference publication with the title “Manufacturing Process Control Through a Digital Twin: Encoding Issues” at the conference TESConf 2020 – 9th International Conference on Through-life Engineering Services. The proceeding of the publication is already published and may be found on the following link: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3718017
The research work of the publication focuses on the CPS communication of the Digital Twin and the implications of the security and safety on the control signals. The work employs a finite element model to consider the virtual part of the Digital Twin and a robust control through the solving an optimization problem in terms of Linear Matrix Inequalities. Also, a RSA cryptography algorithm is utilized for the encryption/decryption of the signals. The effect of the time-varying delays on the system is observed on the tracking for a laser heating process.
