The gain and phase margins of a control system are used to assess its performance. The proposed method estimates the gain and phase margins on-line by a modified relay feedback scheme, where a delay element is embedded between the relay and controller. The estimated results are used to access the goodness of the controller parameters. When the retuning of controller is found necessary, a similar procedure can be applied to tune the PI/PID controller based on specifications of gain and phase margins. Thus, performance assessment and controller improvement can be done simultaneously, which ensures the system to have good performance in control.application/pdf288750 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所性能評估控制器設計增益邊限相位邊限繼電器回饋多環路控制performance assessmentcontroller designgain marginphase marginrelay feedbackmulti-loop control控制系統之性能評估與線上監控(3/3)reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9412/1/932214E002008.pdf
