• 中文摘要： 本文提出ATV之改良法,可用於時延系統之識別。本方法不但可免除在ATV法中以階梯響應試驗求取製程增益之步驟,並可求得正確的轉移函數。但當系統受到干擾時,即使利用具有遲滯的替續器亦無法求得正確的轉移函數,而產生不可避免的模式誤差時,線上韌性控制被用以改良控制系統的控制成效。
• 英文摘要： A modified AutoTune Variation (ATV) method is proposed for system identification of a system with dead time. The step response test to determine the process gain is not required. The process gain is directly obtained from the data of the closed-loop system with a relay. An accurate transfer function of the process is easily obtained using the proposed method. Based on the identified transfer function, robust control is applied. An on-line stability index is used to improve the performance of the control system.
