This paper presents a framework for studying the effects of combined bending and twisting actuation on the aeroelastic performance of highly-flexible active composite wings. The effects of embedded anisotropic piezoelectric strain actuators are consistently accounted for throughout the nonlinear aeroelastic analysis. The nonlinear active aeroelastic analysis consists of an asymptotically correct active crosssectional formulation, geometrically-exact mixed formulation for dynamics of moving beams, and a finitestate unsteady aerodynamics with the ability to model dynamic stall using the ONERA model. Once the nonlinear equilibrium is determined, a linearization about that point yields a set of equations in state space form. From that, different LQG controllers can be designed and the closed-loop system simulated to determine the impact of the anisotropic piezoelectric strain actuators on the stability enhancement and gust alleviation characteristics of flexible wings. A proposed wind tunnel model is presented to illustrate the analysis framework and to show the potential of active aeroelastic tailoring using active fiber composites. Results show that the orientation of the actuators and the electric field profile can be tailored for maximum stability augmentation or for maximum gust alleviation, and that a compromised situation can still have significant improvement in both performance metrics.

This study presents a vibration control using actively tunable vibration absorbers (ATVA) to suppress vibration of a thin plate. The ATVA's is made of a sandwich hollow structure embedded with the electrorheological fluid (ERF). ERF is considered to be one of the most important smart fluids and it is suitable to be embedded in a smart structure due to its controllable viscosity property. ERF's apparent viscosity can be controlled in response to the electric field and the change is reversible in 10 microseconds. Therefore, the physical properties of the ERF-embedded smart structure, such as the stiffness and damping coefficients, can be changed in response to the applied electric field. A mathematical model is difficult to be obtained to describe the exact characteristics of the ERF embedded ATVA because of the nonlinearity of ERF's viscosity. Therefore, a fuzzy modeling and experimental validations of ERF-based ATVA from stationary random vibrations of thin plates are presented in this study. Because Type-2 fuzzy sets generalize Type-1 fuzzy sets so that more modelling uncertainties can be handled, a semi-active vibration controller is proposed based on Type-2 fuzzy sets. To investigate the different performances by using different types of fuzzy controllers, the experimental measurements employing type-1 fuzzy and interval type-2 fuzzy controllers are implemented by the Compact RIO embedded system. The fuzzy modeling framework and solution methods presented in this work can be used for design, performance analysis, and optimization of ATVA from stationary random vibration of thin plates.
