چکیده
The synthesis and experimental validation of an active utter suppression controller for the Active Flexible Wing wind-tunnel model is presented. The design is accomplished with traditional root locus and Nyquist methods using interactive computer graphics tools and extensive simulation-based analysis. The design approach uses a fundamental understanding of the utter mechanism to formulate a simple controller structure to meet stringent design speci cations. Experimentally, the utter suppression controller succeeded in simultaneous suppression of two utter modes, signi cantly increasing the utter dynamic pressure despite modeling errors in predicted utter dynamic pressure and utter frequency. The utter suppression controller was also successfully operated in combination with another controller to perform utter suppression during rapid rolling maneuvers.

H∞ Robust Controller Design and Experimental Analysis of Active Magnetic Bearings with Flexible Rotor System
H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...
متن کاملActive Vibration Suppression of a Nonlinear Flexible Spacecraft
In this article, the issue of attitude control and active vibration suppression of a nonlinear flexible spacecraft is assessed through piezoelectric patches as actuator and sensors. Two controller loops are applied: the inner loop, to make the panel vibration damped through piezoelectric patches; and the outer loop, to perform spacecraft maneuver using the reaction wheel acting on the hub. An o...
متن کاملRobust 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 کاملFlutter Analysis of a Low Aspect Ratio Swept- Back Trapezoidal Wing at Low Subsonic Flow
A linear, aeroelastic analysis of a low aspect ratio swept back trapezoidal wing modeled as a cantilever plate is presented. An analytical and numerical formulation for both the aerodynamic forcing and structural response of the wing was developed. The analytical model uses a three dimensional time domain vortex lattice aerodynamic method. A Rayleigh-Ritz approach has been used to transfer equa...
