Paper Abstract

The SOAR Telescope project has completed development of the Active Optical System (AOS) software system. This paper describes the two Computer Software Components (CSCs) that are part of the SOAR/AOS software. The first CSC is referred to as the Operations Control (OpCon) Software. The OpCon Software contains all of the software necessary for running and monitoring the Adaptive Optics Control System (AOCS). This includes the software to run the Primary Mirror Assembly (PMA), to command the Secondary Mirror Assembly (SMA) and the Turret Controller, to set the modes of the Tip/Tilt mirror, and to monitor and report status from the status data acquisition board. It includes the command and data interface to the Telescope Control System (TCS). It includes the AOCS state logic and the input routines for reading the database of command vectors. The second CSC is called the Database Generation (DBGen) Software. The DBGen Software contains the software that generates the database of PM force vectors and SM command vectors. This software uses either theoretical data or measured wavefront data to build the databases. This paper focuses particularly on the PMA actuator control software. We describe the use of Nastran modeling data for initial deployment of the telescope and the concept for using actual measured data for calibration optimization. We also describe the software implementation designed to allow the actuator control system to meet its timing requirements during telescope slew and to meet the primary figure requirements during telescope observations.
