Model-free vibration control to enable vibration suppression of arbitrary structures

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.
