With the aim of improving the star tracking performance of ground-based telescopes, we deal with the design of model predictive control architecture so as to properly lead their axes while mitigating possible external disturbances affecting the control task. The proposed architecture is composed of two layers, namely, (i) a trajectory generator that determines, based on the astronomic computation, the telescope position and speed references to be tracked while ensuring that all the telescope physical constraints, in terms of speed and acceleration, are never violated; (ii) an model predictive control (MPC) controller that guarantees the optimal tracking of the desired reference behavior by providing the torque inputs for telescope axes for the achievement of star observation task. The control architecture is tailored for the tracking control problem of Telescopio Nazionale Galileo (TNG), located at La Palma (Spain). To this end, by leveraging real data measurements in specific operative scenarios, a 12-order linear system describing the TNG dynamics is identified, via the non-iterative subspace method, for the design of the second layer. Validation results confirm the goodness of the dynamical model in predicting the TNG behavior within the operative range of (80 and 90 deg) altitude position. The effectiveness of the proposed MPC-based control architecture is proven via an ad-hoc virtual testing simulation platform implemented in MATLAB and Simulink and tailored for the identified TNG model. Virtual testing results, involving the real scientific target TYC 1731-916-1, confirm the capability of the proposed solution in ensuring optimal star tracking while mitigating the wind external disturbances forces. Finally, a comparison analysis w.r.t. the state-of-the-art control approaches, i.e., Linear-Quadratic-Gaussian and Proportional-Integrator-Derivative controller, and a robustness analysis w.r.t. the model mismatch between the MPC prediction model and the simulated TNG dynamics are provided to disclose the improved tracking performance achievable via the proposed MPC-based control architecture.

Read Abstract +

MORFEO is the Multi-Conjugate Adaptive Optics Relay for the Extremely Large Telescope (ELT) that will provide multi-conjugate correction of the incoming wavefront by means of three deformable mirrors: one on the telescope and two in the instrument optical train. The wavefront sensing is based on six laser guide stars projected on a constellation of 45 arcseconds and three natural guide stars selected into the 2,7 arcminutes corrected FOV. The current design of the Real Time Computer (RTC) devoted to the deformable mirrors control is reported in the following. According to the ELT architecture, the RTC consists of a Hard Real-Time Core (HRTC) and a Soft Real-Time Cluster (SRTC). The former is in charge of acquiring data from the wavefront sensors and controlling the deformable mirrors and jitter mirrors. It adopts the HEART platform and will be provided by the Herzberg Astronomy and Astrophysics - NRC Canada - which is joining to the Consortium. The SRTC, based on the ESO-provided RTC Toolkit, provides the interface for the Instrument Control System Software. It performs all the supervisory and monitoring tasks, in addition to the auxiliary loops for optimization of correction. This paper will discuss the state of the updated design of the RTC after the Preliminary Design Review (PDR) towards the final design of the subsystem. It will provide an in-depth description of the distributed architecture adopted by the system, with a particular focus on the architecture of the SRTC. Detailed insights into the design considerations, challenges encountered, and solutions implemented in the SRTC architecture will be presented to provide a comprehensive understanding of the system’s current state and future direction. Part of the research activities described in this paper were carried out with contribution of the Next Generation EU funds within the National Recovery and Resilience Plan (PNRR), Mission 4 - Education and Research, Component 2 - From Research to Business (M4C2), Investment Line 3.1 - Strengthening and creation of Research Infrastructures, Project IR0000034 – “STILES - Strengthening the Italian Leadership in ELT and SKA”.

We present the advancements in the development of the scheduler for the Son Of X-shooter (SOXS, 1,2) instrument at the ESO-NTT 3.58-m telescope in La Silla, Chile. SOXS is designed as a single-object spectroscopic facility and features a high-efficiency spectrograph with two arms covering the spectral range of 350-2000 nm and a mean resolving power of approximately R=4500. Its primary purpose is to conduct UV-visible and near-infrared follow-up observations of astrophysical transients, drawing from a broad pool of targets accessible through the streaming services of wide-field telescopes, both current and future, as well as high-energy satellites. The instrument is set to cater to various scientific objectives within the astrophysical community, each entailing specific requirements for observation planning, a challenge that the observing scheduler must address. A notable feature of SOXS is that it will operate at the European Southern Observatory (ESO) in La Silla, without the presence of astronomers on the mountain. This poses a unique challenge for the scheduling process, demanding a fully automated algorithm that is autonomously interacting with the appropriate databases and the La Silla Weather API, and is capable of presenting the operator not only with an ordered list of optimal targets (in terms of observing constraints) but also with optimal backups in the event of changing weather conditions. This requirement imposes the necessity for a scheduler with rapid-response capabilities without compromising the optimization process, ensuring the high quality of observations and best use of the time at the telescope. We thus developed a new highly available and scalable architecture, implementing API Restful applications like Docker Containers, API Gateway, and Python-based Flask frameworks. We provide an overview of the current state of the scheduler, which is now ready for the approaching on-site testing during Commissioning phase, along with insights into its web interface and preliminary performance tests.
