Reduction of the order of a nonlinear system

Abstract

A steam-driven electrical power generating station was designed with the aid of a hybrid computer simulation.In the process, it was advantageous to reduce the order of the system of nonlinear equations describing the boilers and turbines. Since there is no general procedure for reducing the order of nonlinear systems~ each case must be treated individually. However~ the methods used in one system are sometimes applicable to others. The approach taken in the above reduction is presented with this in mind.
