This paper addresses active power flow control of a distributed-parameter planar structure. From the viewpoint of wave propagation, this paper presents a novel power flow control employing vibration intensity as a criterion of vibration energy flow. It enables to generate a quiet zone where structural vibration is completely suppressed in the vibrating structure. Applying cluster feedback control approach, a control method generating a quiet zone on a designated area of the target panel is proposed. Finally, a numerical simulation and an experiment are conducted with a simply supported plate, demonstrating the capability of the active power flow control for generating a quiet zone.
