Robust Control Design for Active Flutter Suppression
Flutter is an unstable oscillation caused by the interaction of aerodynamics and structural dynamics. It can lead to catastrophic failure and therefore must be strictly avoided. Weight reduction and aerodynamically efficient high aspect ratio wing design reduce structural stiffness and thus reduce flutter speed. Consequently, the use of active control systems to counter these adverse aeroservoe...
متن کاملRobust Multivariable Flutter Suppression for the Benchmark Active Control Technology (BACT) Wind-Tunnel Model
The Benchmark Active Controls Technology (BACT) project is part of NASA Langley Research Center’s Benchmark Models Program for studying transonic aeroelastic phenomena. In January of 1996 the BACT wind-tunnel model was used to successfully demonstrate the application of robust multivariable control design methods (H∞ and μ-synthesis) to flutter suppression. This paper addresses the design and e...
متن کاملOptimal and Robust Damping Control for Semi-active Vehicle Suspension
The paper focusses on optimal control issues arising in semi-active vehicle suspension motivated by the application of continuously controllable ERF-shock absorbers. Optimality of the damping control is measured by an objective consisting of a weighted sum of criteria related to safety and comfort which depend on the state variables of the vehicle dynamics model. In the case of linear objective...
متن کاملRobust Controller Design for Active Flutter Suppression of a Two-dimensional Airfoil
This paper investigates the problem of active flutter suppression for a two-dimensional three degrees of freedom (3DOF) airfoil. With the influence of unsteady aerodynamic forces and parametric uncertainties, the output suboptimal control law design for a 3DOF airfoil control system is transformed into a constrained optimization problem. Then, the flutter robust suppression control law could be...
متن کاملModeling the Benchmark Active Control Technology Wind- Tunnel Model for Application to Flutter Suppression
This paper describes the formulation of a model of the dynamic behavior of the Benchmark Active Controls Technology (BACT) wind-tunnel model for application to design and analysis of flutter suppression controllers. The model is formed by combining the equations of motion for the BACT wind-tunnel model with actuator models and a model of wind-tunnel turbulence. The primary focus of this paper i...
