15. Conclusions
This paper shows, by means of an example of a two-degree of freedom missile simulation, a method, in which a bond-graph actuator model can be used to determine the efficiency of a set of controller gains.
This analysis provides a method for comparing the efficiency of controller gains that can be realized in a quick and affordable manner.
