Análise de estabilidade em dinâmica industrial

Abstract

The main objective of this work is to give a contribution to the study and analysis of the stability of systems described by models for "Industrial Dynamics”. To this end, the models are placed under a mathematical formulation suitable for the application of known results about stability; specifically, the second method of Liapunov. Based on such results, with the use of other techniques and the digital computer, an attempt is made to furnish the necessary tools to analize such systems. The first two chapters cover the formulation of the problem, definitions and the most important results on stability. The following chapters consider search and determination of equilibrium points, analysis of sensitivity of these points with respect to changes of the system parameters, and the approach taken for the solution of the problem of determination of the domain of asymptotic stability. A specific example is treated in detail.
