Application of a bandpass filter for the active vibration control of high-speed rotors
Original language description
This study concerns the active vibration control of journal bearings, which are also known as sliding bearings. The control system contains a non-rotating loose bushing, the position of which is controlled by piezoelectric actuators. For governing the respective orthogonal direction of the journal motion, the control algorithm realizes a proportional controller in parallel with a bandpass filter of the IIR type. The bandpass filter is of the second order and its centre frequency is self-tuned to be the same as the whirl frequency that results from the instability of the bearing journal due to the oil film. The objective of active vibration control is to achieve the highest operational speed of the journal bearing at which the motion of the rotor is stable. The control algorithm for the active vibration control is implemented in Simulink and realized in a dSPACE control system.
