- Abstract
Mechanism of aeroelastic control is more complicated than that of vibration control based on piezoelectric material, and analyzing the control mechanism is of great significance for the research of aeroelastic control. The macro fiber composite (MFC) actuator is modeled by the load simulation method. The control law of the aeroelastic model is designed by the negative velocity feedback algorithm. The effects of the additional aerodynamic force and the piezoelectric driving force on the aeroelastic control system are studied, and the control mechanisms of the system are analyzed. The results show that the additional aerodynamic force can improve damping behavior of the aeroelastic open-loop system below the flutter velocity. With the increase of airflow velocity, the damping effect of the additional aerodynamic force on the aeroelastic closed-loop system is increasingly strong, but that of the piezoelectric driving force on the system becomes gradually weak. In aeroelastic control, the energy consumption of the system is mainly dependent on the additional aerodynamic force, which is obviously different from the control mechanism that in vibration control.
