Design of a candidate flutter suppression control law for DAST ARW-2

Abstract

A control law is developed to suppress symmetric flutter for a mathematical model of an aeroelastic research vehicle. An implementable control law is attained by including modified LQG (Linear Quadratic Gaussian) design techniques, controller order reduction, and gain scheduling.An alternate (complementary) design approach is illustrated for one flight conditionwhereln nongradient-based constrained optimization techniques are applied to maximize controller robustness.
