摘要: Several control design approaches were utilized recently for actively stabilizingthe 2 and 3 degrees-of-freedom (DoF) aeroelastic wind section, whichhave structural nonlinearities. The present paper focuses on the stabilizationof DoF model. proposed strategy takes into accountthe uncertainties of trailing edge dynamics robust output feedbackcontrol is designed where only measurable state variable pitch angle.Beside asymptotic stability, controller has to fulfill criteria relatedto bound l2 norm signal. basedon Tensor Product (TP) type convex polytopic representation DoFaeroelastic wing section model all performance objectivesare formulated via Linear Matrix Inequalities (LMIs). TP typepolytopic obtained transformation as first step ofthe feedback observer gains are derived LMI basedconvex optimization second step. resulting observertakes structure NATA derivedcontroller evaluated validated numericalsimulations.
