Abstract

The research conducted by the authors is concerned with the simulation of active noise control within a plate-cavity system by the action of primary vibrational inputs acting on the flexible plate. Comparisons between vibration and acoustic control strategy as well as the influence of sensor and actuator numbers are pursued. Simplicity of the geometric model as well as the understanding of the nature and characteristics of modal behaviour account for the choice of the physical model. Simulated control schemes include the use of vibration control inputs (point, line, surface forces and line moments) acting on the flexible plate and acoustic control acting within the cavity (speakers). The following discussion is limited to the development of the analytical basis and the comparison of results obtained in a case studied by Pan et al
