Low order H∞ Robust Controller design for active vibration control

The noise and vibration cancellation is important for precise control, especially for aeronautics, astronautics and advanced manufacture. A low order H∞robust controller is designed for the active vibration control by using the magnetostrictive actuator. XY-centering algorithm is employed to design the low order H∞robust controller. The numerical simulation solution shows the vibration is reduced more than 20dB using the designed H∞robust controller, which order is lower than the order of generalized actuator model. The real-time experimental solution is also given to show that the designed controller is efficient.
