本文是利用牛頓類型預測器的預測方式做衍伸,而衍伸的部份可視為系統未來的連續訊號之時間函數,此方法稱之為多項式預測器(Polynomial Predictor)。透過基本的數學運算,即可得到簡便的預測公式來進行多步預測。為了能夠有效的壓抑系統波形振盪之情形,將此預測器加入回授控制(Feedback Control)作探討分析;比較回授控制的差異性,因此運用了脈波輸入訊號來進一步控制預測的輸出值,經改善後的多項式預測器也不需作繁雜的計算,能夠壓抑系統輸出之波形,而這種多項式預測器回授控制的方法,將稱作為比例脈波控制(Proportion Pulse Controller)。
Polynomial predictor is used by the Newton type method. The extension is through the basic mathematical operations. The simple calculated formula is obtained for multi-steps prediction. The result of the predictor is taken for feedback control. The controller is used to suppress the vibration of the system, but for low-frequency system is emerged poor. So the pulse input is introduced to improve the difference of the predictable feedback control. The system is called Proportional Pulse Control. The controller is no need to make complicated calculations, and it can be suppressed the high amplitude of the output waveform.
