Abstract

The paper deals with the on-line model, control strategy of smart rotor blades and controller realization. After the overview of the smart blade, a recursive MX filter is developed for simulating the dynamic features of smart blades, in which the coefficients have certain relationships with the rotor’s natural frequencies and modal damping, etc. Then a new hybrid adaptive control strategy is presented. It combines an adaptive feedforward controller with a conventional feedback controller, and brings about the increase of the modal damping of the controlled blade and the cancellation of the disturbance response. Finally, two Motorola DSP56002EVM boards are used for other control law. The dramatical reductions are obtained for the vibrations induced by single frequency, dual frequency, varied frequency and varied amplitude excitations.
