Abstract

This paper describes the application of linear quadratic Gaussian (LQG) methodology to the design of active control systems for suppression of aerodynamic flutter. A wind tunnel model of a research wing with associated sensors and actuators comprises the system to be controlled. Results of a synthesis methodology that provide small values of rms response and robust stability are presented. Results of control surface and sensor position optimization are also presented. Both frequency response matching and modal residualization are used to obtain practical flutter controllers.
