摘要:
温度漂移误差是位移传感系统的主要误差之一.为了提高位移传感器输出的精度与稳定性,可以把位移传感器的输出与温度传感器的输出进行数据融合.提出一种基于RBF网络(径向基函数神经网络)的多传感器数据融合方法,把位移传感器和温度传感器的输出送入融合中心,通过RBF网络的学习训练,得到稳定的位移输出.实验表明:在相同的温度波动情况下,位移传感器的输出稳定性比原来提高了约4倍.该方法在位移传感系统减小温度漂移的应用中十分有效.
Abstract:
The tem perature dr ift e rror is one o f the m ajor e rrors of the displacem ent senso r system. In order to improve the accuracy and stability, the output from the displacem ent senso r and the one from the temperature sensor can be fused. At present, neu ra l netwo rk has been w ide ly app lied to the area o f da ta fus ion, in w hich da ta from mu ltiple sensors arem ostly fused by BP neura l netw ork. The low training speed o f BP ne tw ork leads to the poor practicab ility, there fo re in this paper, a data fusion m ethod based on RBF neura l netwo rk is proposed for reduc ing temperature drift erro r. The outputs from the disp lacem ent sensor and tho se from the tem pera ture sensor are sent to the fusion cente r, w he re the RBF neura l netw ork is tra ined and as a resu lt the stable outpu t is obta ined. Exper iments show that the ou-t put stab ility of the disp lacem ent sensor is im proved by 4 tim es under the sam e tem perature fluctuation. It is obv ious that the proposed me thod in this paper is effective for reduc ing the drift erro r o f displacem ent sensor system.
