本文介绍了多输入部分极点配置结构振动抑制的导纳法的理论和实际应用。已经证明了与传统的矩阵方法（例如基于有限元的状态空间控制）相比，接受度方法的许多优点，特别是不需要知道或评估结构矩阵M、C、K，并且在实际实验中，可以概括“接受度”的测量，使得致动器动力学的显式建模变得不必要。振动主动控制实验证明使用两个试验台。在第一组实验部分极点配置应用到一个轻量级的玻璃纤维梁使用宏纤维复合材料（MFC）的致动器和传感器。在第二组实验中，主动振动控制是在一个沉重的模块化测试结构上实现的，该结构代表了使用电磁致动器和压电（ICP）加速度计的不同动态复杂性的系统。它表明，所选择的极点可以被分配到预定的值，而不影响其他感兴趣的极点的位置。
The theory and practical application of the receptance method for vibration suppression in structures by multi-input partial pole placement is described. Numerous advantages of the receptance method over conventional matrix methods such as state-space control based on finite elements have been demonstrated, in particular there is no need to know or to evaluate the structural matrices M, C, K and in practical experimentation the measurement of ‘receptance’ may be generalised so that explicit modelling of actuator dynamics becomes unnecessary. Active vibration control is demonstrated experimentally using two test rigs. In the first set of experiments partial pole placement is applied to a lightweight glass-fibre beam using macro fibre composite (MFC) actuators and sensors. In the second set of experiments active vibration control is implemented on a heavy modular test structure representative of systems of differing dynamic complexity using electromagnetic actuators and piezoelectric (ICP) accelerometers. It is demonstrated that chosen poles may be assigned to predetermined values without affecting the position of other poles of interest.
