技術簡介

引發工廠控制迴路震盪型擾動的因素很多，如控制器參數調整不當、閥件磨損、外部干擾都有可能使迴路產生擾動，而當全廠性擾動發生時，由於迴路眾多且成因不明，常無法即時有效處置。全廠擾動源追溯技術的目的在於如何快速而有效地從眾多震盪的迴路中找出引發擾動的可能源頭，並於鎖定問題迴路後再由工程人員進行測試與診斷，找出確切原因。

Abstract

There are many factors that cause factory control loop oscillation disturbances, such as improper adjustment of controller parameters, wear of valve parts, and external disturbances, which may cause disturbances in the loop. When plant-wide disturbances occur, they often cannot be processed immediately because of the numerous loops and unknown causes. The purpose of the disturbance source tracing method is to find out the source of the disturbance quickly and efficiently from many oscillating loops, and after the problem loop is highlighted, the engineering personnel carries out testing and diagnosis to find out the exact root cause.
