One-Dimensional Modeling For Compressor Engine Controls

In modeling and control of power equipment, mathematical models are often used to develop robust control systems. The models are used both in the calculation of performance metrics and in determining control set-point parameters. These one-dimensional control functions require a method to determine an output value given some known input parameter. This article will describe various mathematical modeling methods that are used in compressor unit control systems as well as the advantages and disadvantages of each method. One-dimensional mathematical models are used extensively in sophisticated modern control systems. Generically these models are: y=f(x) (Eq. 1) Where x is an independen
