基于模型的主动振动控制存在一些问题。当目标结构的特性发生变化时，需要保持闭环系统的性能和稳定性。此外，控制性能和稳定性取决于模型的精度。在本研究中，提出了无模型振动控制系统，可以抑制任意结构的振动。利用与被控对象相对应的虚拟结构模型可以实现振动抑制。使用独特的无模式控制器对多种类型的受控对象进行控制仿真，验证了控制系统的有效性和鲁棒性。
There are some problems in model-based active vibration controls. It is required to maintain performance and stability of a closed-loop system when characteristics of a target structure change. In addition, the control performance and stability depend on the accuracy of the model. In this study, model-free vibration control system to enable vibration suppression of arbitrary structures is proposed. Vibration suppression can be realized by using the model of virtual structure corresponding to the controlled object. The effectiveness and robustness of the control system are validated by control simulations with several types of controlled objects using a unique mode-free controller.
