摘要 误差传感器的最优布放是有源声学结构研究的关键问题之一,它对控制效果的好坏和控制系统的复杂程度有决定性的影响。研究了基于近场测量面声压传感的结构声辐射估计问题,给出了两种基于测量面声压的有源控制目标,在此基础上研究了误差传感器的最优布放规律。结果表明:误差传感器应布放在有源控制后测量面声压最小的区域内,一般分布在次级结构的周围,误差传感器的个数与次级结构的个数相等时,即可取得良好的有源控制效果。 Error sensor arrangements for active acoustic structure(AAS) is theoretically investigated in this paper. Error sensing strategies for active acoustic structure based on nearfield pressures are examined. Two kinds of cost functions using nearfield pressures are given. According to theoretic analysis and computer simulations, the optimum arrangements for error sensors in active acoustic structure are obtained.
