Empirical Evaluation of Powerplant Dynamics for Computer and Field Performance Monitor Applications 620291

A method of developing a mathematical model of power-plants to simulate engine-governor, or servo systems on a d-c analog or digital differential analyzer is presented.
Based on experimental data, the steady-state output of a powerplant is defined as a function of two variables. The dynamics is defined, and the steady-state performance is corrected for response and inertia effects. The resulting mathematical model is discussed with respect to computer applications, instrumentation, and techniques for compiling empirical data needed.
Another application is monitoring performance of farm tractors, industrial equipment, and/or automotive systems under field operating conditions. The mathematical model is simulated by an analogous circuit of components that may be inconspicuously mounted on the powerplant in question.
