近年来，随着工业的发展，对控制系统性能指标的要求越来越高。例如，在轻型列车的控制的情况下，不仅在单一频率上而且在宽的频率范围上都应该减小由对柔性体的干扰和共振的影响引起的振动。对于这个问题，传统上使用干扰观测器。然而，在工业系统的许多情况下，例如重量轻的列车，干扰频率在某些频率范围内变化。因此，使用传统的干扰观测器可能难以减小干扰的不利影响。在本研究中，我们利用干扰观测器来实现振动抑制控制系统，以科普频率变化，以减少周期性干扰的不利影响。为了证明所提出的干扰观测器的有用性，我们将其应用到振动控制系统的柔性梁的干扰力，其频率是在一定范围内变化的。数值仿真和实验结果表明，与传统的干扰观测器和H∞控制器相比，所提出的控制方案具有上级的抗干扰性能。
Recently, requirement for performance specifications of the control systems has been very severe with the advance of industry. For instance, in the case of control of the light weighted train, vibration caused by an influence on a disturbance and resonance of flexible body should be reduced not only at a single frequency but also on the wide range of frequency. For this problem, disturbance observer has been used traditionally. However, in many cases of industrial systems such that the light weighted train, disturbance frequency is varied for some frequency range. Therefore, it may be difficult to reduce the adverse effect of the disturbance by the use of the traditional disturbance observer. In this study, we implement the vibration suppression control system using disturbance observer to cope with frequency variation to reduce the adverse effects of periodic disturbances. In order to demonstrate the usefulness of the proposed disturbance observer, we applied it to the vibration control system for a flexible beam where disturbance force whose frequency is varied for some range is imposed. It can be shown by numerical simulations and experiments that the proposed control scheme has superior performance of disturbance reduction as compared with the traditional disturbance observer and the H∞ controller.
