This paper concerns the minimizaton of acoustic potential energy in a strongly coupled structural/acoustic enclosure using both active noise control (ANC) and active vibration control (AVC) A target enclosure is composed of rigid walls and a flexible panel that is subject to external forces. First, optimal feedforward control law to minimize the acoustic potential energy in the enclosure is derived using control actuators for AVC and acoustic point sources for ANC situated at arbitrary locations. It is found that acoustic control power becomes zero under the optimal condition even in a strongly coupled enclosure as in a weakly coupled system. It is also found that under the minimization of acoustic potential energy, vibration control power becomes zero. Numerical simulation is carried out, demonstrating the control effect for minimizing acoustic potential energy using both ANC and AVC. Finally, synergy effect of ANC and AVC is clarified, intriguing phenomenon due to the effect being investigated.
