Abstract

MICADO (Multi-AO Imaging Camera for Deep Observations), the ELT first-light imager, will face the impact of windshake and vibrations, especially on tip and tilt modes. Standard integral control fails to reach MICADO-SCAO targeted performance. The presented data-driven predictive tip-tilt controller accounts for the variability of observational conditions and is shown to efficiently manage this windshake and vibration issue. We show how the impact of M4 temporal dynamics can be simulated without increasing the simulation sampling period and we assess performance with these dynamics for both regulators.
