Abstract
Ground-based telescopes play a key role in astronomical research by observing celestial objects from the Earth's surface. These telescopes are equipped with large mirrors or lenses to collect and focus light from distant stars, planets, galaxies, and other cosmic phenomena. They are essential for a wide range of studies, including stellar evolution, planetary formation, and the detection of exoplanets. Indeed, compared to space-based telescopes, ground-based telescopes offer the advantage of being more easily maintained and upgraded making them invaluable tools for long-term astronomical surveys and real-time observation of transient events, such as supernovae and gamma-ray bursts. However, even if they are limited by atmospheric distortion, optimal seeing and light pollution, ground-based telescopes are expected to remain a cornerstone of observational astronomy thanks to continued technological innovations. Indeed, several innovations have been provided over the past year to overcome the mentioned limitations and improve astronomical observations. In particular, new adaptive optics systems are being deployed to address atmospheric distortion, while more suitable sites have been proposed and protected in order to mitigate light pollution and improve seeing. Based on this, and thanks to the improvement of industrial technologies, ever larger telescopes are being designed so to allow the study of farther celestial bodies. In this framework, the novel ground-based telescopes require a tracking control system more accurate in terms of both hardware and control algorithm.\\ The aim of the thesis is to provide new control solutions based on optimal approaches which aim at improving the ground-based telescope tracking control systems by leading them to achieve more accurate performance.
