Abstract In this study the use of many stand-alone devices is considered for active vibration control. A stand-alone device represents a control unit which is able to independently perform the vibration control task, since it is embedded with sensors, an inertial actuator and a microcontroller, in which the control algorithm is implemented. The aim of this architecture is to improve the performance of a decentralized control strategy through a partial sharing of data between devices, without the use of cables. The proposed algorithm also aims to avoid instability phenomena related to the dynamics of inertial actuators. First, the formulation of the modified Negative Derivative Feedback resonant controller is derived; then, the steps of the control strategy are explained, which are based on a preliminary modal identification of the structure and an automatic assignment of a compensator for each resonance frequency to be controlled. Finally, the proposed method is validated with experimental results from a clamped-clamped beam.

基于选择性负微分反馈算法的分布式无线控制策略

摘要 在这项研究中，考虑使用许多独立设备进行主动振动控制。独立设备代表能够独立执行振动控制任务的控制单元，因为它嵌入了传感器、惯性致动器和微控制器，在其中实现了控制算法。该架构的目的是通过在设备之间部分共享数据而不使用电缆来提高分散控制策略的性能。所提出的算法还旨在避免与惯性致动器的动力学相关的不稳定现象。首先，推导了改进的负微分反馈谐振控制器的公式；然后，解释控制策略的步骤，它基于结构的初步模态识别和为每个要控制的共振频率自动分配补偿器。最后，所提出的方法通过夹钳梁的实验结果进行了验证。
