摘要

本文的目的是对已经完成的研究进行概述，目的是找到解决格兰泰克望远镜10米直径主镜噪声抑制问题的控制器。首先，提出了一种大规模MIMO系统的动力学解耦方法。基的改变使解耦成为可能，成为控制目的的重要结果。除此之外，由于解耦，用镜子的比例模型进行测试的可能性特别有趣。其次，对该模型进行了描述，并利用ARMAX模型对其进行了动态辨识。最后，对比例模型分段低频噪声抑制控制器的设计进行了讨论，并给出了结果。

Rejecting the low-frequency noise in the 10m diameter primary mirror of the GRANTECAN telescope

The goal of this paper is to provide an overview of the studies that have been done with the aim of finding a controller that solves the noise rejection problem in the 10m diameter primary mirror of the Grantecan Telescope. In the first place, a method for decoupling the dynamics of this large-scale MIMO system is presented. A change of basis makes the decoupling possible, becoming an important result for control purposes. In addition to this, the possibility of making tests with a scale model of the mirror is specially interesting thanks to the decoupling. Secondly, this scale model is described and its dynamic identified using an ARMAX model. Finally, a discussion about the design of a controller for low-frequency noise rejection in the scale model's segments and the results obtained are presented.
