Beschreibung:
  • Analyzing the structure of an aircraft’s electrohydraulic actuation system, the traditional realization of the closed–loop system shows a considerable limitation of dynamics. 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.
