The Octoglass company has specially developed its own controllers for electrochromic glass control. The controllers are based on the created theoretical basis, on which the physical model of the electrochromic device is based. The mathematical model created on the basis of the physical model allows one to carry out computational experiments both with a virtual electrochromic device and to investigate the parameters of a real sample of an electrochromic system. On the basis of a mathematical model, both the characteristics of the electrochromic device planned for creation and the parameters for the device control algorithms are developed. The obtained parameters are used to configure the control controller for the safe control of a specific electrochromic glass. All this work has been done to ensure that the quality of our products is always excellent.
