IEC闪变仪的数字化实现与改进
Research of Digital IEC Flickermeter
依据IEC闪变仪的测量原理，建立灯-眼-脑环节的数学摸型，并运用双线性变换实现数字化。借助MATLAB及其仿真工具，完成了数字式IEC闪变仪的仿真，针对仿真结果，本文对瞬时闪变视感度的收敛时间和视感度加权滤波器方面做了改进。并按照IEC的校验标准，结果完全能满足精度要求。
ccording to IEC’s design principles, the light-eyes-brain model is established,and Bilinear transform is used to achieve digital. With MATLAB and its simulation tool, the simulation of digital IEC flickermeter is completed. For the simulation results, the convergence time of the instantaneous flicker visual sensitivity and visual sensitivity weighting filter are improved. In accordance with IEC calibration standard, the results fully meet the required precision.
