Enhanced control concepts like state control enable a remarkable improvement. Gradually, the outlined descriptive design procedure leads to a robust sampled–data controller, which automatically manages the parameter uncertainties and finite wordlength effects, occuring in low hardware performances or with rapid sampling. These considerations are verified by extensive simulations and real tests. Finally, a conceivable application is presented regarding to the interaction of actuator dynamics and the flexible structure of an airfoil.enhttp://rightsstatements.org/vocab/InC/1.0/Primary flight control systemhydraulic actuatorsampled data controlrobust controlparameter space designdelta-transformationA unified control strategy for flight control actuatorsConference Paper2006-04-12urn:nbn:de:gbv:830-opus-300710.15480/882.235LuftfahrzeugtechnikAktorFlugzeugbauLuftfahrttechnik11420/23710.15480/882.235930768569Other
