摘要
依据某声音导引系统的设计要求,提出了一种位置控制算法,并建立了数学模型.利用该算法,根据3个声音接收器的接收时间差,可精确计算出移动声源的位置坐标,并可使用移动声源位置的监控信息对干扰声波进行过滤,从而达到提高系统控制精度的目的.
According to the design request,locality arithmetic was proposed for the sound guide system,and calculating model was also given.Using the arithmetic,the coordinates of moving sound source can be caculated accurately based on the different time that the sound arrived at the three receivers.Interferential waves can be filtrated using monitor information of moving sound source in order to improve control precision.
