Development of Reduced Order Models for control System Design Using the OPTSYSX Program.

Abstract

The modern controls engineer is often faced with designing a system which is characterized by a large number of first order differential equations. It is highly desirable and sometimes necessary that such complex systems be reduced for analysis, synthesis and implementation into a physical control system. It is the intent of this thesis to present a mathematical procedure and computer software based upon this procedure which enable the control engineer to construct reduced order models. As examples, two large order systems are analyzed: a sixteenth order model of the F100 turbofan engine and a ninety-eighth order model of the X-29A aircraft control system. Additional Keywords: OPTSYSX Computer program; OPTRED Computer program; Interfaces; Fortran; Computations; Notch filters.
