An Overview of the Receptance Method in Active Vibration Control

This paper describes the practical application of the receptance method for active vibration control of real structures. The method uses in general the measured transfer function between the input/output data including the dynamics of the actuators and sensors. Therefore, it does not require knowledge or evaluation of the system matrices M, C, K, which usually contain modeling errors. This would be the main advantage over conventional matrix methods. The method is developed for partial pole placement and robust pole placement. The receptance method is applied to a modular test structure, which can have different configurations, in which one of these configurations in the form of ‘an ‘H’ is presented in this paper. The vibration modes including the torsional modes were controlled using the single-input state feedback control. The method is also applied to an Agusta-Westland W30 helicopter airframe in the vibrations test house at Yeovil.
