An application of prony signal analysis in controller design for multimachine systems that is based on incorporates both local and interarea electro - mechanical oscillatory modes is introduced . 4 簡要介紹了基于gps廣域測量的prony方法在pss設(shè)計(jì)中的應(yīng)用,并研究了其在擾動(dòng)統(tǒng)一性問題的應(yīng)用,得到初步結(jié)果。
Y type and s type dual - path saw mass sensors have been tested and analysed in detail . their frequency domain characteristics and time domain characteristics have been tested under non - oscillatory mode . transmission characteristics of y type s type and " - " type saw mass sensors are derived by p matrix representation . primary delay signal triple reflection signal and quintuple reflection signal of these sensor devices have been analysed in detail 結(jié)果表明,在正常工作模式下, y型和s型雙聲路聲表醚質(zhì)量傳感器件的三次渡越反射信號(hào)和五次渡越反射信號(hào)比“一”字型雙聲路聲表醚質(zhì)量傳感器件的三次渡越反射信號(hào)和五次渡越反射信號(hào)分別小12db 、 16 . 67db和n _ . sdb ? 17 . 3db 。
