In addition, a closed-loop structure has been designed for the identification. On the other hand, the relay feedback test is also a popular identification method under closed-loop. A novel approach using relay feedback test for identification is proposed in this project. During the identification, an automatic adaptive mechanism is presented to eliminate the effect of unknown disturbance. Both of these identification methods are useful in the monitoring and diagnosis of dynamic systems.application/pdf137009 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所次空間識別法脈衝響應序列閉環架構繼電器回饋測試subspace identificationimpulse response sequenceclosed-looprelay feedback testreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9384/1/922214E002022.pdf
