MELT is an optical test bench with a turbulence generator, whose main objective is to deploy and validate key functionalities of central control system and the Wavefront control strategies on the Extremely Large Telescope (ELT) during AIV/commissioning and operation phase. The subsystems under control are: a segmented primary mirror, a secondary mirror on a hexapod, an adaptive fourth mirror, a fast tip/tilt mirror, phasing sensor, a light source, a Wavefront sensor, a IR camera, together with their control interfaces that emulate the ELT conditions. The Core Integration Infrastructure will be deployed to MELT for their verification and testing strategy, producing feedback to their requirements and design. This paper describes the Control SW distributed architecture, communication patterns, user interfaces and SW infrastructure. The control algorithms are being developed separately and will be integrated into the control loop via MATLAB scripts.
