This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink. An LQR controller has been developed to control both electrical engines turning the turn table and the antenna beam. This report contains an analysis of the model and the controller. The conclusion from this project is that the turn table and the antenna beam can be controlled to fulfill the requirements for the system.
