| Abstract: | Under dense phase conveying conditions of powder flow, powder velocity is very fast, its pulsation is large. The essential method for processing powder flow signals is described based on LMS Algorithm. Firstly, Spatial filtering effect of capacitance sensors is studied. Secondly,The LMS criterion is used to estimate pulse response function to seek peak value. This algorithm can reduce the convolution smeared influences of correlation algorithm. Finally, the processing results of practical measured signals are given. |
