Abstract
The adaptive optics systems for the next generation of extremely large telescopes have in some cases exceeded the capabilities of single computers and servers. The next generation of real-time control systems for these adaptive optics systems often consist of multiple “nodes” connecting into a real-time system, with supplementary computers which optimise and supervise the real-time loop. In this presentation we will give an overview of the approach we are taking to the HARMONI Adaptive Optics control system. We will describe the approach we have taken in designing, modelling, and building a real time control system for this scale of instrument.
