This control technique helps to minimize the deleterious effects of optical defects in the system. We propose to use system identification on open-loop and closed-loop and frequency response analysis to achieve a better tuning and characterization of a POLC system. Our results show that system identification can be used to determine the robustness of the system, and can also be used to obtain a model for system tuning.STAMPAenArticle10.1007/s12036-022-09846-32-s2.0-85138291436https://link.springer.com/article/10.1007/s12036-022-09846-3https://api.elsevier.com/content/abstract/scopus_id/85138291436FIS/05 - ASTRONOMIA E ASTROFISICA
