Abstract

Real-time data smoothing of noisy process signals using the moving average method and exponential smoothing filter are useful in process control. However, they have a large time phase delay, and control is very difficult to apply for processes having a large time delay. In this paper, a very simple way using modified moving average method is introduced. This method is applied to practical concentration signals. The proposed method is very easy to design, and an effective way to reduce a large time phase delay
