Research on Adaptive Vibration Control of Smart Rotor Blade

Deals with the real time simulation of smart rotor blade vibration control. A real time simulation system is constructed. The key units of the system are two Motorola DSP56002EVM boards. One of them is used as a rotor blade dynamics simulator, the other controller. In the simulator, two recursive MX filters are responsible for the responses caused by disturbances and controllers, respectively. In the control strategies, adaptive feedforward control and a presented hybrid control are studied. The hybrid control combines an adaptive feedforward controller with a conventional feedback controller, and can control the modal damping and the responses of smart blades simultaneously. The simulator and the controllers are realized by the special assembly language. The dramatical vibration reductions are obtained for harmonic excitations.
