Practical Technique for Forming an Analog Computer Model of Process Element

Abstract

Forming a simple but sufficiently good analog computer model for each element of a process plant is a technique of great practical import in designing and analyzing a large system. A novel way to the solution of this problem was suggested by Paynter and Takahashi in 1956. In practice along this principle, however, one faces the following two immediate questions : i) Given a particular process element, how can one select the most appropriate type of transfer function to simulate it? ii) How can one conveniently determine the numerical values of the parameters when the number of such parameters is more than three? The technique developed here will nicely answer the questions and allow one to make a unique choice for the required model as the result of a straightforward process of model-forming.
