In conjunction with the High Luminosity upgrade of the Large Hadron Collider, the ATLAS detector is also undergoing an upgrade to handle the significantly higher data rates. The muon end-cap system upgrade in ATLAS, lies with the replacement of the Small Wheel. The New Small Wheel (NSW) is expected to combine high tracking precision with upgraded information for the Level-1 trigger. To accomplish this, small Thin Gap Chamber (sTGC) and MicroMesh Gaseous Structure (Micromegas) detector technologies are being deployed. In order to successfully integrate, commission, monitor and control both detector technologies on NSW, various Detector Control System (DCS) applications need to be developed. The standard industrial control software used at CERN is WinCC OA. Through WinCC OA, a Supervisory Control and Data Acquisition framework has been established to maximize synergy between all experiments. ATLAS is hierarchically organized in a tree-like structure of detectors, followed by sub-detectors, sub-systems for each detector, etc. Thus, the ATLAS DCS must conform to this structure. Moreover, it is tasked to be a coherent and safe for operation interface for all sub-detectors of the experiment. It must also be able to bring the detector into any desired operation state, allow automatic or manual actions, report abnormal system behavior to operators, monitor and archive all parameters necessary for the experiment. Due to the installation location of NSW in ATLAS, the effects of Barrel Toroid and End-Cap Toroid magnets on the sub-detectors must be measured. For the final experiment at ATLAS, each NSW large sector will be equipped with Hall sensors to monitor the magnetic field near the NSW. This readout is accomplished with an Embedded Local Monitor Board called MDT DCS Module, all of which is monitored by the corresponding control system. Since the Micromegas is a gaseous type particle detector, all parameters of the gas system have to be monitored. The ATLAS Gas Group has implemented the monitoring according to the design of the gas system and thus, the DCS has to also confronm to the same scheme. Data from each sensor both in the gas mixer and distribution modules is published and monitored by the DCS. At the same time, alarms for all important parameters will bring operational statuses and states to every component of the gas system. This thesis will describe both the commissioning and development of the two above mentioned control systems. (EN)
