Force Feedback Control Method of Active Tuned Mass Damper

الملخص EN

Active tuned mass dampers as vibration-control devices are widely used in many fields for their good stability and effectiveness.

To improve the performance of such dampers, a control method based on force feedback is proposed.

The method offers several advantages such as high-precision control and low-performance requirements for the actuator, as well as not needing additional compensators.

The force feedback control strategy was designed based on direct-velocity feedback.

The effectiveness of the method was verified in a single-degree-of-freedom system, and factors such as damping effect, required active force, actuator stroke, and power consumption of the damper were analyzed.

Finally, a simulation study was performed by configuring a main complex elastic-vibration-damping system.

The results show that the method provides effective control over modal resonances of multiple orders of the system and improves its dynamics performance.
