We present the adaptive optics (AO) real-time control (RTC) systems used in two Extremely Large Telescope (ELT) instruments. We will discuss the common architecture of the AO RTC systems used by HARMONI and MOSAIC instruments and highlight the use of the Durham Adaptive Optics (DAO) control software. By leveraging the commonality in these systems, we can accelerate development and minimize redundant efforts.
