The design and operation of these systems are affected by the detector\u2019s cavern harsh environment consisting of high magnetic fields and radiations. This work presents a feasibility study for aerial inspection and mapping around a CERN particle detector using a robotic Lighter-than-Air (LtA) Unmanned Aerial Vehicle (UAV), specifically a blimp. Firstly, mission scenarios and the detector environment are introduced; in this context a new empirical model is proposed for the estimation of magnetic disturbances resulting from the interaction of electromagnetic motors with the external magnetic field. Subsequently, the design of a reference blimp and the control system is presented, comparing different control techniques, namely, Computed Torque Control (CTC), Sliding Mode Control (SMC) and Nonsingular Terminal Sliding Mode Control (NTSMC). Finally, the results of trajectory tracking simulations are reported, considering both the uncertainties of the dynamic parameters and the estimated magnetic disturbances. This work demonstrates that the blimp successfully follows desired trajectory, navigating complex environments while maintaining stability and accuracy. Despite the challenges posed by high magnetic fields, indoor blimps can effectively offer safer and more efficient approaches to facility surveillance and maintenance, reducing radiation exposure for human personnel and minimizing detector downtime.<\/jats:p>","DOI":"10.3389\/frobt.2023.1238081","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T07:15:13Z","timestamp":1697181313000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Mission analysis, dynamics and robust control of an indoor blimp in a CERN detector magnetic environment"],"prefix":"10.3389","volume":"10","author":[{"given":"Francesco","family":"Mazzei","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Teofili","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabio","family":"Curti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corrado","family":"Gargiulo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,10,13]]},"reference":[{"key":"B8","volume-title":"FCC-Hh: the hadron collider","author":"Abada","year":"2018"},{"key":"B7","volume-title":"FCC-Ee: the lepton collider","author":"Abada","year":""},{"key":"B52","volume-title":"HE-LHC: the high-energy large hadron collider: future circular collider conceptual design report volume 4.
