Rezumat: The adaptive system of vibration damping for finite-element model of helicopter composite main rotor blade was designed. This control system include a neural network controller based on reference model, a bunch of distributed sensors measuring the local deformations in vibrating structure and piezoelectric power actuators acting on structure by local bending and twisting torques. The mentioned controller adjust a behavior of finite element model close to behavior of reference beam model that have a best parameters of structural damping, vibration stability and weight balancing. The control system model implemented in MATLAB Simulink© have shown an essential decrease of vibration level and suppression of rotor blade finite element model dangerous auto oscillations.
