Abstract :
This paper presents the development of 3-axis ADCS (Attitude Determination and Control Sub-System) simulation and controller for a geostationary satellite using the Ptolemy II software framework. The simulator determines satellite current attitude and minimizes the error by means of a Linear Quadratic Regulator (LQR). A model of satellite dynamics is derived and linearised, and a control system is designed for it. The same control system is then used to control corresponding non-linear model. Simulation graphs and Java3D visualization is presented to demonstrate success of simulation and effectiveness of the ADCS controller.
