Abstract

The synthesis design of multi-input/multi-output (MIMO) low-order control laws of the Flutter Active Suppression (FAS) system for an Active Aeroelastic Wing (AAW) is presented via Linear Quadratic Regulator/Robust (LQR/Robust) method. Weighting matrixes of linear quadratic cost function, reduction method and accelerometer position are also discussed using singular values of the return difference matrix as robustness index and system insensitivity to gust as constraint. The control laws with various design performances determined by various design velocity points and robustness requirements are given successfully. It is shown that the synthesis method is available and convenient for engineering application of FAS control law for MIMO aeroservoelastic (ASE) system.
