Paper Abstract

This paper presents a semi-active flutter control strategy for a high-aspect-ratio (HAR) wing using multiple magnetorheological (MR) dampers. In this paper, the aeroelastic behavior of the system is first investigated by establishing the aeroelastic equations of a HAR wing-aileron system. The strip theory is employed for calculating the unsteady aerodynamic loads. Then the semi-active aeroelastic control system with multiple MR dampers is modeled. The clipped-optimal control algorithm is performed for controlling the MR dampers to suppressing the flutter of the aeroelastic system. A passive flutter control of the system is also performed for the purpose of comparison. Numerical simulation results show that the semi-active control strategy based on multiple MR dampers holds promise in suppressing the flutter of the HAR wing-aileron system.
