Technology of Unmanned Combat Aerial Vehicle (UCAV) is one type of aircraft that is favorable in military sector because its ability which resembles fighter aircraft and unmanned. The need of unmanned aircraft is getting more diverse, one of them is in control segment. Control system is one of the aircraft’s modernity parameter because fighters are required to agile and stable. One of the advanced abilities of the control system of UCAV is able to do multimode flight. Basically, multimode flight is the process to cut the connection (decoupling) between variables that automatically connected each other (coupling), for example in lateral-directional mode. Therefore, this research focused on designing the control system that able to decouple the variables that affecting each other so the multimode flight can be achieved. Control design in this research used eigenstructure assignment method. Unlike root locus and pole placement, eigenstructure is not only assign eigenvalue but also eigenvector. Eigenvalue is parameter to determine the stability of the system, while eigenvector plays role in giving form of the response. Since eigenvector affects the shape of the response, multimode flight can be achieved by assigning the eigenvector value. The simulation was done using Command Augmentation System (CAS) with adding the error state as the tracking reference. Using this method, it needed only one error state because of the advantage of decoupling using eigenstructure.
