Event details

An overview of the receptance method in active vibration control is presented by Dr Maryam Ghandchi-Tehrani.

An overview of the receptance method in active vibration control is presented.  The method has significant advantages over conventional methods such as state-space. The method is entirely based on the measured data and it does not require any knowledge of system matrices M, C and K, therefore it avoids any mathematical modeling such as FE models, which can have assumptions and approximations. The receptance method has developed for single-input and multi-input control. The problem of pole placement is considered using the receptance method. Pole placement is particularly applicable to helicopters for the control of vibrations due to the blade passing frequency. Partial pole placement and robust pole placement are also developed using the measured receptances. The method has applied to several laboratory structures and also implemented on Agusta-Westland W30 helicopter.
