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.
