Abstract
Robust control theory deals explicitly with the uncertainties in the characteristics of the aircraft and in the environment in which it has to operate. A modern approach to robust control is H ∞ optimal control. Generally, uncertainty in a model is present at various components and is in this way highly structured. The influence of the structured uncertainty on system performance can be analysed by applying μ-analysis. A combination of the techniques of H ∞ optimal control and μ-analysis is known as μ-synthesis. This method has been applied to the design of an Autopilot for RCAM, using μ-synthesis inner-loop controllers. The formal criterion of the μ-synthesis method could not be met by these controllers. However, the resulting design performs rather well.
The NLR contribution to GARTEUR Action Group FM(AG08) was funded by the Netherlands Agency for Aerospace Programs.
