Research of Active Noise Control for Transformer Based on Piezoelectric Ceramic Actuator
A common source of noise is operational excitations of mechanical devices,which cause vibrations and thus sound radiation from their surfaces.Plate and shell structures in transformer,vehicle or airplane applications vibrating in resonance show particularly high noise levels.Classic methods of noise reduction such as passive damping or anti-noise are not efficient enough in certain cases.Therefore,the use of structural control for reduction of sound radiation is presented in this paper.A piezoelectric ceramic actuator (PCA) for the active noise control is also proposed.The structure of the proposed PCA is discussed and the control method of the structure is carried out.The proposed PCA has excellent performance compared with conventional ones,such as more force,convenient installation and disassembly.The active noise control (ANC) system and control algorithm are also discussed in this paper.The performance of the proposed controller is analyzed through simulation in the Matlab/ Simulink.
