Abstract

In this paper the observed-based realization of a given complex controller is used to derive an architecture suitable for its implementation. That is, an architecture in which physical tuning parameters are highlighted and can be adjusted as useful potentiometers. This approach is based on the well-known Youla controller parameterization, but its specific feature is that the on-board model, on which the observer-based realization is built, does not correspond to the synthesis model. A particular application, for which such a controller architecture is very interesting, is the implementation and adjustment of flight control laws during flight tests. Actually, the on-board last tuning is based on physical considerations and required only a few potentiometers to improve flying qualities in situ. The results presented in this paper concern the lateral flight control law of a highly flexible aircraft which have been synthesized by a modern robust control approach.
