MARST (Multi-channel Antarctic Solar Telescope) aims to observe the Sun inmultiple wavebands in Antarctica and will be China's first solar telescope inAntarctica. The telescope has two tubes, corresponding to Photosphereobservation which uses 11 filters and Chromosphere observation in H{\alpha}waveband. The two tubes need to be coordinated to observe at the same time. Thetelescope will observe the Sun for a long time, so a self-guiding module isneeded to improve sun tracking. Besides, performing solar specific flat-fieldexposure is necessary for analyzing. EPICS is introduced to control eachhardware and an autonomous observation system based on RTS2 is designed undersuch demands. EPICS application modules are implemented for each device:telescope mount & focuser, filter wheel, H{\alpha} filter, dome with webcams,Andor CCD and PI CCD. We also integrate EPICS modules into RTS2 framework withan XML format configuration. To control these applications autonomously we havedeveloped a RTS2 executor module where two plan classes are instantiated tocontrol two sets of filters and CCDs, and to ensure only one could control themount at the same time. Different types of observation plans are designed todescribe different series of processes with different priorities. To improvesun tracking, we calculate the centroid of each image to get the offset, thenapply the correction to the telescope during observation process. For frontendusers, a GUI based on PyQt5 and QML is implemented and connects to rts2-httpdand rts2-proxy modules so that users can control devices, check images and getlogs.
