- 中文摘要:
類比計算機(analog computer)在解決工程問題上是一種有效且迅速的計算工具,借助於類比模擬可以改善工程之設計,通常工程系統之動態特性(dynamic characteristic)可以用微分方程式表示,如用微分方程式直接建立模擬程式,必須先作微分方程式解答最大值之估計,用此估計值標度(scale)微分方程式使其適合類比計算機操作,這方法必須憑據豐富之經驗或試誤法(trial and error) 。本文介紹用狀態方程式表示工程系統 ,以狀態變數之方式建立類比模擬程式,其過程簡捷便利,尤其在作計算機標度處理時,不必如傳統方法先估計解答之最大值,然後再分開兩次各別作大小與時間之標度。本文所介紹之方法可不必估計最大值,而且大小與時間標度一次處理,節省做程式所需時間及充分發揮計算機之精確性。
- 英文摘要:
The analog computer has been a fast andeffective calcutating equipment. With the helpof analog simulation on this equipment, we canmake a perfect engineering design. Generally,the dynamic characteristic of engineering systemcan be expressed in differential equations. Ho-wever, prior to processing simulation directly,we should estimate the maximum value of sol-ution and scale such differential equations foranalog computer. This method should be basedon experience or trial & error. The purposeof this article is to provide a new method-"state variable approach to anolog simulation".which is a short cut for programming. By thisway, we need not estimate the maximum valueof solution for scaling, thus, the time of programming is saved, and the accuracy of analogcomputer is fully facilitated.
