A μ-synthesis Controller design is presented to study the robust performance for the vertical acceleration control of a B-52 longitudinal aircraft model with flexibility taking into account specific input and output multiplicative uncertainty models. The aircraft is assumed to be flexible and subjected to severe wind gusts causing undesirable vertical acceleration. We use the Von Karman gust power...
This paper investigates the problem of active flutter suppression for a one-dimensional two degrees of freedom airfoil with leading and trailing edge flap control. The goal is to design an active flaps control capability to suppress the flutter instability and enhance the sub critical aero elastic response to time-dependent external pulses. A new interpretation for the modeling of the airfoil is given...
The recent development in the aeronautic domain is characterized by a high flexibility aircraft which results in a stronger interaction between the flight control system, structural and aerodynamic. The robust control is needed to meet the desired performance specification. This paper presents a robust control of flexible aircraft wing using LQR, LQG/LTR and H2 / H∞ techniques. In the first step a...
