"23520" . "Pardubice" . "The task of the active vibration damping of vanes in the wind tunnel was proposed to research a relative motion of the turbine vanes. The system in the wind tunnel contains the eight vanes. The active vanes have their natural frequency approximately 84 Hz and the damping ratio ξ = 0.015. Therefore the control system and the identification process must satisfy the requirements on the high speed. The system REX was used for real-time control. The autotuning controller is based on the frequency identification, the internal model principle and the state feedback control and the controller parameters are obtained by the pole placement method. Two industrial PCs with the operating system PharLap were used to control these oscillating vanes. The main aim of this article is the presentation of the designed control algorithm and the measured results."@en . "Active vibration damping of vanes in wind tunel"@cs . . "4"^^ .
